Vs static PAT

A network architecture looks like this: PIX firewall, inside private public static IP (192.168.1.1) and the local network of private static IP 192.168.1.0 255.255.255.0, outside (only one address available public IP, for example, 172.18.124.216).

For the guests of LAN access to the outside as the internet, of course, a CARESS is necessary. That's a lot for a single translation.

Now for everything outside hosts to access inside web server for example 192.168.1.2, licensed and the translation of intellectual property must be made. Usually, the translation will say:

static (inside, outside) tcp 172.18.124.216 www 192.168.1.2 www netmask 255.255.255.255 0 0

(1) as I understand it, from inside to outside is PAT, many-to-one, while from outside to inside is one-to-one static translation. Is this correct? How could the two many-to-one, and one co-exist on the same PIX?

(2) what the last two 0's to the statement above (0 0) Static?

Thank you for helping.

Scott

Yes, you already have the idea.

--> inside outside, pat

--> outside inside, 1-1 (port forwarding)

PIX can handle these two translation as they work in a particular direction. When pix receives a packet destined for the internet from the inside, it is mapped to the pat statement because the stream is insid--> out; Otherwise, when pix receives a packet from outside, it will match the static port forwarding instruction. again, it works because of the leadership.

regarding the second concern, these two 0 see max_conns and emb_limit respectively.

According to the pix command line reference,.

max_conns means the simultaneous maximum number of tcp and udp for the whole subnet connections; Whereas emb_limit means the maximum embryonic connections per host.

in other words, these parameters can be used as a countermeasure to attack back.

  • Public static PAT in Nat/Global conflicts

    I seem to have a problem because of a conflict between the static PAT and nat/global pool.

    I have a config with the following static and ACL. (192.169.10.2 and 192.168.10.3 are two address on the same adapter on the same server)

    static (dmz, outside) tcp 212.xx.xx.4 www 192.168.10.2 5080 netmask 255.255.255.255 0 0

    static (dmz, external) 212.xx.xx.5 192.168.10.3 netmask 255.255.255.255 0 0

    line 100 access list 7 permit tcp any host 212.xx.xx.4 eq www

    100-list access line 8 permit tcp any host

    212.XX.XX.5 eq ftp

    line 9 of the access list 100 permit tcp any host 212.xx.xx.5 eq ftp - data

    With this new configuration when I issued the "cl" xlate I outwardly use the site and the FTP site.

    However, as soon as the (192.6.12.2/3) server to connect to the internet the static PAT stops working:

    static (dmz, outside) tcp 212.xx.xx.4 www 192.168.10.2 5080 netmask 255.255.255.255 0 0

    It is interesting the individual static (ftp) continues to work:

    If I do a "show xlate" he mentions a 'Global 212.xx.xx.22 192.168.10.2 Local. " That's probably why it does not work as it comes to take an address from the global pool and is no longer uses 212.xx.xx.4. I don't know why this conflict happens? Any help much appreciated.

  • static PAT statements, need help...

    Hi all

    I am trying to set up a mail server, for the time being for reasons that I explain not rather, I can't put it on the demilitarized zone. So he is sitting inside the 515e Firewall interface.

    I have the internal IP address of the server as 192.168.50.13 and inside the network I can send, receive, email etc. on this server. This is a new server, so I recently install my a records and MX. When the rattling of the entrance to the area the correct IP address is now assigned domain name. However, I can't see my e-mail server in the outside world. When you run a DNS query on the MX record, I get no response.

    The problem is at the level of PIX. My static instructions do not seem to work.

    One of my works of 4 static instructions (for our Services Terminal Server server), but the 3 other entries are not.

    They are as follows:

    static (inside, outside) MainOffice 3389 192.168.50.75 tcp 3389 netmask 255.255.255.255 0 0

    static (inside, outside) tcp smtp MainOffice 192.168.50.13 smtp netmask 255.255.255.255 0 0

    static (inside, outside) tcp MainOffice 192.168.50.13 pop3 pop3 netmask 255.255.255.255 0 0

    static (inside, outside) tcp MainOffice telnet 192.168.50.201 telnet netmask

    255.255.255.255 0 0

    (the last entry is just to test and see if I could even host a standard telnet server from my local office win2k and see through the firewall, the test has failed, I can telnet in via the local IP address,.201, but not through the external IP, MainOffice.)

    As often elsewhere in the config PIX seem to affect issues that I :), I included a complete running-config list below for those who would like to reference. Thank you for your time,

    Another strange thing of note, with this current config I can't ping my IP external interface starting from IP external or internal IP. I have my entries ICMP set and thought I should be able to see, but can't. It is not as important a question as the above question.

    Hi Okumura,

    A loss of packets via Internet VPN is not out of the normal. This could be a problem with traffic ESP packet loss

    If you still experience this problem then check with your ISP if the ISP is clean, then you can contact TAC to open a new case and we can help you further.

  • Two static NAT/PAT instructions

    Hello

    I have a PIX 515 running PIX OS 7.0, and I have a server behind the PIX with a static translation entry.

    I was invited as a remote site must connect to the SQL service running on this computer, but the site connects to a non Standard-SQL TCP port, so I thought that I can use a static PAT (port forwarding), but I wonder... can I keep the existing static NAT and add the static PAT? !!! Furthermore, the rest of the remote sites will connect to the same SQL service on the standard port and there are more services running on the server that will be accessible from the outside.

    The server is online, so I won't add the static PAT before you make sure that it will run smoothly...

    Thnx, Salem.

    Hi Salem,

    First, I entered this static NAT command:

    static (inside, outside) 1.2.3.4 10.0.0.1 netmask 255.255.255.255

    This static PAT order tracking:

    static (inside, outside) tcp 1.2.3.4 http 10.0.0.1 netmask 255.255.255.255 http

    and got this error message:

    ERROR: mapped address conflict with existing static

    This suggests that it is not possible.

    Kind regards

  • PAT for two web servers

    Hi all.

    I want to change the MS ISA for Cisco ASA server, but I have problem with PAT.

    The two addresses are published under the same internet address 1.1.1.1 MS ISA server configured static PAT for two web servers, example.web1.com inside the address 192.168.1.10 and example.web2.com inside the address 192.168.1.11.

    When the user try to open the web page example.web1.com the internet ISA Server MS create translates an internal address 192.168.1.10

    When the user try to open the web page example.web2.com the internet ISA Server MS create translates an internal address 192.168.1.11.

    In the cisco example uses single address:

    static (inside, outside) tcp 1.1.1.1 192.168.1.10 www www netmask 255.255.255.25

    but I have two web servers uses the same port 80 and even outside of the address 1.1.1.1

    SAA can create translation URL? For example:

    static (inside, outside) tcp example.web1.com, www www 192.168.1.10 netmask 255.255.255.255

    static (inside, outside) tcp example.web2.com 192.168.1.11 www www netmask 255.255.255.255

    Hello

    To my knowledge, this type of NAT is not possible in the SAA.

    The ASA has nothing to differentiate the 2 translations to eachother other than the order of the NAT configurations. But I think that at the level of your software it doesn't accept even the second NAT configuration that it overlaps with the first. In the most recent software that it would accept the second configuration, but the traffic would still be hit only one of the NAT configurations.

    There must be something on the ISA MS who, in addition to NAT overlapping, knows that static PAT choose based on the requested web page?

  • Static nat and NAT ACL 0

    All,

    I have nat 0 ACL indicating that an ip address should not be natted, while a static nat statement saying we need natted. I just want to know that we will have precedence.

    Thank you

    It is of the order of operations PIX nat / ASA.

    the NAT 0 acl_name (nameif) has priority.

    1 nat 0-list of access (free from nat)

    2. match the existing xlates

    3. match the static controls

    a. static NAT with no access list

    b. static PAT with no access list

    4. match orders nat

    a. nat [id] access-list (first match)

    b. nat [id] [address] [mask] (best match)

    i. If the ID is 0, create an xlate identity

    II. use global pool for dynamic NAT

    III. use global dynamic pool for PAT

  • VPN client and contradictory static NAT entries

    Hello, we have a VPN IPSEC implemented on a router for remote access. It works very well, for the most part. We have also a few PAT static entries to allow access to a web server, etc. from the outside. We deny NATting from the range of IP addresses for the range of VPN client and it works except for entries that also have PAT configurations.

    So, for example, we have web server 10.0.0.1 and a PAT redirection port 10.0.0.1: 80 to the IP WAN port 80. If a VPN client tries to connect to 10.0.0.1: 80, the syn - ack packet back to the customer WAN IP VPN on the router! If the VPN client connects to the RDP server 10.0.0.2:3389, it works very well that this server is not a static entry PAT.

    Is there a way to get around this?

    Thank you!

    There is a way to get around, use the same settings you have for your dynamic nat in your nat staitc entries, something like this:

    Currently, it should show as:

    IP nat inside source static XXXXX XXXX 80 80

    you need to take it

    IP nat inside source static 80 XXXX XXXX 80 map route AAAA

    When your itinerary map YYY refers to something with an acl that you refuse traffic from inside your router for the pool of vpn

    IP Access-list ext nonat

    deny ip 10.0.0.0 0.0.0.255

    Licensing ip 10.0.0.0 0.0.0.255 any

    route allowed AAAA 10 map

    You even need all the static PAT

  • NAT 0 0 nat nat static ACLs

    Anyone know what the order of nat/static... .is it nat 0 acl, nat 0, static, nat? where nat 0 acl is first and nat is the last... for example if I have an address that meets the criteria of nat 0 acl, nat 0, static, NAT... what happens?

    John

    Order of preference for the translation goes as follows:

    (1) nat 0 access-list (free of nat)

    (2) match against existing xlates

    (3) static

    (a) nat public static with no access-list (first match)

    (b) public static pat with no access-list (first match)

    (4) nat

    (a) nat access-list (first match) Note: nat 0-list of access is not part of this command.

    (b) nat (best match) Note: when you choose a global address of multiple pools with the same id of nat, the following order is tried

    (i) if the id is 0, create an xlate identity.

    (II) use the global pool for dynamic NAT

    (III) use the global pool for PAT dynamic

  • Public static political static NAT in conflict with NAT VPN

    I have a situation where I need to create a VPN site-to site between an ASA 5505 using IOS 7.2 and a Sonicwall NSA4500. The problem arises where the LAN behind the Cisco ASA has the same subnet an existing VPN currently created on the Sonicwall. Since the Sonicwall cannot have two VPN both run on the same subnet, the solution is to use policy NAT on the SAA as well as for the Sonicwall, the new VPN seems to have a different subnet.

    The current subnet behind the ASA is 192.168.10.0/24 (The Sonicwall already has a private network virtual created for another customer with the same subnet). I try to translate it to 192.168.24.0/24. The peer LAN (behind the Sonicwall) is 10.159.0.0/24. The ASA relevant configuration is:

    interface Vlan1

    IP 192.168.10.1 255.255.255.0

    access extensive list ip 192.168.24.0 outside_1_cryptomap allow 255.255.255.0 10.159.0.0 255.255.255.0

    list of access VPN extended permit ip 192.168.10.0 255.255.255.0 10.159.0.0 255.255.255.0

    public static 192.168.24.0 (inside, outside) - list of VPN access

    card crypto outside_map 1 match address outside_1_cryptomap

    In addition, there are other static NAT instructions and their associated ACLs that allow certain traffic through the firewall on the server, for example:

    public static tcp (indoor, outdoor) interface smtp SERVER smtp netmask 255.255.255.255

    The problem is this: when I enter the static strategy statement NAT, I get the message ' WARNING: real-address conflict with existing static "and then it refers to each of the static NAT statements reflecting the external address to the server. I've thought about it, and it seemed to me that the problem was that policy NAT statement must be the first statement of NAT (it is the last one) so that it is run first and all traffic destined to the VPN to the Sonicwall (destination 10.159.0.0/24) tunnel would be properly treated. If I left him as the last statement, then the other static NAT statements would prevent a part of the 10.159.0.0/24 network-bound traffic to be correctly routed through the VPN.

    So, I tried first to my stated policy NAT upward in the ASDM GUI interface. However, moving the declaration was not allowed. Then I tried to delete the five static NAT statements that point to the server (an example is above) and then recreate them, hoping that would then move up the policy statement NAT. This also failed.

    What Miss me?

    Hello

    I assumed that we could have changed the order of the 'static' , the original orders, but as it did not work for some reason any then it seems to me that you suggested or change, that I proposed should work.

    I guess that your purpose was to set up static political PAT for the VPN for some these services, then static PAT of public network access, then static NAT to policy for the rest of the network in-house.

    I guess you could choose any way seems best for you.

    Let me know if get you it working. I always find it strange that the original configuration did not work.

  • From single to multiple IP addresses external IP traffic internal

    We are transitioning to a Symantec SMS to a Cisco ASA 5505, and I'm running into a lot of trouble to replicate our configuration for inbound traffic. We currently have a Setup something like this:

    (Of course I pick up a bunch of arbitrary numbers here.)

    1.2.3.4 port one--> 10.1.0.1 port one

    1.2.3.4 port b--> 10.1.0.5 port b

    1.2.3.4 port x--> 10.1.0.20 port p

    1.2.3.4 port is--> 10.1.0.21 p port

    1.2.3.4 port z--> 10.1.0.22 p port

    1.2.3.4 is the unique external IP address we use for traffic that passes through, and 10.1.0.x internal host. x, y and z are ports chosen arbitrarily in a sequence.

    I'm doing it via the ASDM. The ASA is running 9.1 2 software and I use ASDM 7.1 (3). I'm trying to accomplish this by using Configuration > firewall > public servers.

    What I do is the following:

    1. In Configuration > firewall > objects > network objects/groups, create objects for the external IP address and all internal hosts.
    2. In Configuration > firewall > objects > objects/Service groups, create objects TCP ports x y z, and a TCP object for p port (which is not in the default set). Protocols on ports a and b are in the game by default, so they do not need to be defined.
    3. In Configuration > firewall > public servers, add a series of entries of public server with the external host as public IP, address the external interface as the public Interface, the internal as the private Interface interface, the host in question as IP address private, and in the case the two first entries, the protocol chosen as the private service sector. In the case of the last of three entries, I also selects "public address specify if it is different from the private Service. This will allow the static PAT. "I then selects the associated service from port p as the private Service and the service associated with the ports x, y or z (respectively) in the public service.

    .. .or at least, that's what I'm trying to do. I have encountered the following problems:

    1. If I do not use 'Specify the public address if different of the private service', the first mapping I do works very well and pass the traffic correctly. If I do, it does not. (I'm testing it trying to connect from the outside and I get a connection in the case of the former, but not in the latter scenario.) I generally choose tcp/aol as my test "public service" and are trying to connect to the external IP address on port 5190, which is the port for tcp/aol.)
    2. At the time wherever I try to do a second mapping, the system rejects saying «server address configuration comes into conflict with a rule of existing translation»
    3. Even if it worked, when I select "Public address specify if it is different from the private service", it only shows me the list of integrated service objects, not everything I've created. This isn't really the end of the world - I could divert just a series of services that we do not - but it would be nice if I could get actually ports my users are already using so that I could make a transparent exchange rather than giving them all the new connection information.

    Any thoughts would be greatly appreciated. I guess I'm missing something pretty obvious, but I'm not that knowledgeable about the Cisco ASA family at this point, I can probably use a few pointers get this working.

    Thank you!

    Hello

    There's something really weird happens with the end of your post. The second section of numbered points has its text completely messed. The lines of text are on top of eachother.

    I don't personally use the ASDM at all to configure ACL and NAT configurations.

    I could help with the configuration of CLI format however.

    Seems that you are trying to configure static PAT (Port Forwarding) for several internal hosts using the public IP address unique who will be on the external interface of the ASA.

    In general, you can use this format for all NAT configurations

    network of the object

    host

    NAT tcp service interface static (inside, outside)

    Naturally, the names of the interface may be different and could be "udp" instead of "tcp". Also since you can configure a large number of these I suggest you come up with a clear policy naming for your 'network of the object' so that they are easy to read and to clarify the purpose.

    Each 'object' that is created can be used on your external interface ACL to allow traffic. However if you want to configure a large number of these configurations PAT static and there are several ports for host even then it might be easier to make different 'object' to be used in the ACL list or it can be annoying.

    Could resemble a basic ACL corresponding to the "nat" above configuration rule

    access list permit tcp any eq object

    Once again the ACL above may look different in your use. You can limit the traffic of certain source addresses that would mean multiple ACL lines.

    Hope this helps

  • 2 ISP, Router 1, 2 servers.

    Forgive any ignorance in the matter. I have an ASA 5515 - x on my place of work, and we've just added a second service provider to one of the interfaces. We have two servers within our network and we want each server to use one of the internet connections that the ASA is connected. Is there a way I can put a server to send all of its contents on a pipe and the other server through another, without each interfere with each other. Any help would be appreciated. Thanks in advance.

  • Cisco ASA 8.4.1 address Destination NAT?

    I have a situation where I have a deployed asa5505 8.4.1 running.

    The customer has a mail server existing which is located on their local network and has Port configured NAT for normal mail ports, etc. 25,110,993,587.

    It works very well for incoming mail and any jerky mail user off the external server or by visiting the webmail from outside the network.

    However when the users within the LAN to connect through the ASA test back entering the IP address on the external Interface of the ASA, they are unable to do so.

    I came up with the solution is split DNS.   well does he rely on users not changing their dns servers.

    I was wondering if it is possible to make a sort of NAT that rewritten traffic destined to the above ports on the external IP address to the internal LAN Ip instead.

    This is probably a stupid question, but I couldn't find an answer may I use the terms wrong to get one.

    In any case, I was hoping someone here could point me in the right direction.

    Thank you

    You can only configure DNS rewrite rewrite if you have static NAT 1 to 1, with static PAT as advised, rewriting DNS is not supported because with PAT static, it is potentially different internal IP mapping, so the DNS rewrite is not exactly at the right address.

  • Cisco forwarding port does not

    Dear experts, I got a production Firewall (Cisco Pix 515e 6.3 (1)) and I have set up to allow access to the outside on a server (SSH only).

    Access-group 101 in the interface inside

    When you access from the Wan, I used putty SSH port 2022 a.b.c.d IP in and he gave me of waiting times. I used the:

    Capture interface capo outside access-group 100

    The results were (that I can remember that I am not on site):

    My WAN IP-> a.b.c.d (R)

    My WAN IP-> a.b.c.d (S)

    My WAN IP-> a.b.c.d (S)

    My WAN IP-> a.b.c.d (S)

    The server on the internal LAN access is great and I can access port 22 on the server on the local network (Note: there is a L3 switch in the environment and inside the IP segments are 10.0.1.0/24 and 10.0.5.0/24 routable both.)

    This is what I did so far and would like more ideas on this subject that I am currently facing to. thanks!

    Hello

    Configuring static PAT (Port Forward) seemed correct to me.

    If you use the IP address of ' outside ' interface you would generally configure the parameter "interface" , and not the IP address.

    public static interface 2022 22 netmask 255.255.255.255 tcp (indoor, outdoor) 10.0.5.200

    Of course if you can/want to save a public IP address for this server only you could configure static NAT

    public static 10.0.5.200 (inside, outside) subnet mask 255.255.255.255

    That would bind essentially those 2 IP addresses, and you can allow services that are needed for the current server. Naturally, you will also need to allow traffic in the external ACL to the new public IP address.

    But it should also work with your configurations. If you want to use the IP address or a separate public IP's to you.

    If you are missing the 'road' to the 10.0.5.0/24 subnet in your PIX configuration so it is an obvious problem in why the server is inaccessible from the Internet. So, I would start by adding the "itinerary" necessary and retest. If it does not then would be good to verify that the routing between the server and the PIX is fine. For example, there is a route to the PIX server, and the server has a default route takes traffic to the PIX.

    Hope this helps

  • The ASA with crossed VPN Port forwarding

    Hello

    I worked on a question for a while and I have managed to track down the issue, but I don't know how to solve the problem.

    I have an ASA 5505 8.4 (7) running with a tunnel for incoming remote users anyconnect vpn. I also want to configure incoming Web server port forwarding.

    The question seems to be traversed rule which stops incoming port forwarding:

    NAT (outside, outside) NETWORK_OBJ_172.16.1.0_28 interface description dynamic source hairpin to natting users vpn on the external interface

    When I disable the port forwarding will work perfectly (according to tracer packet that is).

    I have attached the config to this post. I would appreciate any idea how to get the through VPN and the transfer to the incoming port working.

    The config has been condensed to remove unneed config.

    Thank you

    Hello

    What is the configuration commands, you use to put in place the static PAT (Port Forward)?

    The problem is most likely order of the NAT configurations such as configuring NAT above in the upper part of the NAT configurations.

    Configuring static PAT, that you could use to make it work would be

    the SERVER object network

    host

    service object WWW

    tcp source eq www service

    NAT (server, on the outside) of the interface to the static SERVER 1 source WWW WWW service

    The above assumes the source for the host interface is "Server" and the service that you want to PAT static TCP/80.

    Note that we add the number '1' in the 'nat' command. This will add at the top. The same should be done for any other static PAT you configure you want for these VPN Clients.

    Hope this helps
