• PIX 501 NAT / PAT problem

  Have a 501 for a client configuration. All works well for a few minutes and they the PC can't get out the firewall. Looks like the NAT works very well but the PAT do not hit.

  This part of the config, I received an example of cisco.

  Can someone help me?

  Thank you

  Fred

  With less than 25 PCs behind the PIX you won't have to worry about memory problems. You will have to look for good of licensing issues. The default 501 supoprts 10 users license and can be upgraded to support 50 users - still no need to worry about memory.

  Regarding the counters on the PIX, I usually recommend to leave all timers with settings by default unless you are having problems and TAC allows you to change them.

• router in 1921 with the double nat ADSL problem

  I have problems with the implementation of a router in 1921 with double lines ADSL for failover. For some reason any internet traffic keeps using Dialer 1 as internet main connection, while 2 Dialer should be primary. Also, when I finish my NAT with allowed a full acl, it translates the public ip address of the 2-to-1 Dialer the Dialer before she sends in the internet.

  This is my config:

• Connection of the PS3 - WRT610N - NAT Fail problems

  Hi all

  Since I bought the PS3 in December, I was running that it connected to my Linksys WRT610N router.  The day that I have configured it first, it all detected automatically and off I went to play.  A few times, I've moved to the bedroom and played wireless.  In addition to entering the router WPA key, it does everything automatically.

  Today, the dang thing connects to the PS network.  I spent the last few hours troubleshooting 8.  I will list every little thing I did, but I have to ask myself why I never had to redirect the front ports, or anything else.

  I came to the conclusion that it is my router which is the main problem, because when I plug directly into the cable Modem, I have no problem.  Ironically, all my other devices operate on the router - phones, laptops, desktops, wireless TV and Wii.

  When I try the connection test, I get:

  -Obtain IP address succeeded

  -Internet connection successful

  -PlaystationNetwork failed

  I am able to surf the internet with the browser on the PS3 at this point, but no PSN.

  When I look at the connections and status, I get:

  -Internet connection enabled

  -Wired connection method

  -Speed and detection automatic duplex

  -Address manual settings

  Address - IP 192.168.1.20

  -Subnet Mask 255.255.255.0

  -Default router 192.168.1.1

  -Primary DNS 4.2.2.2

  -Secondary DNS 192.168.1.1

  -MAC address XX (no need to share this!)

  -MTU                           1365

  -Proxy server do not use

  -Available UPnP

  NAT - Type failed

  "Error code 80710092.

  I tried practically all the ideas of 7 hours of internet research has to offer on the following topics: "Unable to connect to PSN" and "failure of NAT:

  1. 1. -My PS3 has given a static IP address
     2. -Pedaled through different DNS numbers
     3. -Changed the MTU size
     4. -UPnP turned on and outside
     5. -NAT disabled
     6. -Someone said all ports are required
     7. -Enabled DMZ for the PS3 static IP
     8. -Off any other device trying to use wireless
     9. -Router firmware update
     10. -Restored by default on the router
     11. -Off "Filter anonymous Internet requests" (against my better judgment)
     12. N ' matter what firewall disabled (against my better judgment)

  There are only two things that I considered that I read by train:

  -Restoration of my default PS3

  It does not appear that this would be the issue but because it connects to the NHP when it is connected directly to the cable Modem.

  -To reset my router VRAM

  Looks like a longshot.

  Can anyone help me please with other ideas?  It's driving me crazy!

  Thank you very much in advance.

  I tried all the suggestions without result.  Now the problem is solved well.

  Solution?  The intensity of my internet cable signal was too weak for the router to divide anything.  That's what the tech explained to me in any case.  I was at-22dBmV and minimum of society is - 10 at the end of the cable (computer, PS3).  The technology fixed a bunch of bad junctions in the House and then realized that I was at-10 in front of my computer now.  He said that a line technician would be fate soon to take a look at the line coming because it is especially where the weakness is.

  As soon as he left, I turned on my PS3.  I got a connection NAT2.  Playstation Network still not, but it of because Sony sucks and has been offline for a while.  I'm sure that it will work as he recognixes the network is stopped and got a NAT2.

  Thank you all for the suggestions.  The moral of the story: do not exclude anything when troubleshooting.  I was sure to have been the router and waited several days before calling the service provider.

  If you're curious of your modem stats, most have an IP address to dial.

• Rule NAT VPN problem

  Hello people, I had a lot of trouble trying to solve this problem, but hoping someone here can enlighten me.

  I have a remote site that hosts a number of services that we manage remotely with an IPSec VPN connection. When connecting to the site connect us very well and can make most of the actions like RDP and connect to servers for maintenance, but a service fails to connect unless I have add a NAT rule exempt to the configuration of the router (ASA 5505).

  Once this rule in place service work, but other services that initially worked work stoppage. In short, this rule must be in place while doing a single task, but then contracted for other tasks. I hope that there is some sort of rule or behavior, I can add to the ASDM configuration makes it so I don't have to manually add this rule whenever I connect.

  Here are the details of the rule:

  access-list 1 permit line outside_nat0_outbound extended ip 192.168.15.192 255.255.255.192 192.168.15.0 255.255.255.0

  NAT (outside) 0 outside_nat0_outbound list access outside tcp udp 0 0 0

  When the connection is established without the rule in place the ASDM syslog shows these warnings:

  Deny tcp src inside: outside:10.100.32.203/135 dst61745 by access-group "inside_access_in" [0x0, 0x0]

  The strange thing is 10.100.32.203 is IP internal my host computer. This is not yet the external IP address of the network I connect from.

  Is it possible a problem with the VPN pool using a subset of the subnet of the VIRTUAL LAN inside? Inside VLAN is 192.168.15.0/24 and the VPN is 192.168.15.200 - 250. I am ready to reconfigure the VPN address pool but need to do remotely, and am unaware of how to do this reconfiguration safely without losing my remote access, since physical access to the router itself is currently very difficult.

  If more details are needed, I am happy to give them.

  Hi GrahamB,

  Yes, the problem with too much running in subnet.

  There are a lot of private-address available, so please create a new group policy and tunnel-group and fill

  pool separate to value ip address and remote with it, when the new cluster to solve your problem, can safely remove the old one.

  I hope this helps.

  Thank you

• Networks VPN NAT l2l problem-Dup-HELP!

  I use a router IOS as a VPN L2L device to connect my site to several different customer locations, some of them use the same internal IP addresses.  These VPNS have been working well.

  I recently added another client to this system and I am now having a problem with the new configuration.  With this configuration, I have NAT my internal addresses.  NAT works correctly, but it NAT my bad common NAT addresses and therefore do not generate the tunnel.

  My internal IP 10.10.x.x

  incorrect NAT pool 10.129.x.x

  decent NAT pool 10.99.x.x

  Help... :))

  Thank you

  The problem is simple. You have almost an identical ACL for two guests. As the first NAT rule has been added previously, it comes into play. To resolve this issue, you must set explicit host/subnet destination match instead of 'none' keyword.

  For example like this:

  ip access-list extended ME-CRYPTO-ACL
    permit ip 10.129.40.0 0.0.0.255 host 10.10.131.63
  ip access-list extended ME-NAT-ACL
    permit ip 10.10.10.0 0.0.0.255 host 10.10.131.63
  ip access-list extended SA-CRYPTO-ACL
    permit ip 10.96.21.0 0.0.0.255 host 10.99.2.95
  ip access-list extended SA-NAT-ACL
    permit ip 10.10.10.0 0.0.0.255 host 10.99.2.95
  

  Another solution is more complex and harder to understand (and explain), you can use Virtual models with tunnel-protection for each customer, VRF and NAT for common services.

• Bizzare vShield Edge-NAT/VPN problem Post - 5.1 upgrade

  Hoping someone can shed some light on this issue for us - the TLDR is that NAT rules seem to be causing unexpected behavior on the VPN traffic after a vCloud 1.5 to 5.1 upgrade.

  Background: We work with a hosting provider to manage our vCloud environment. Quite simple - 2 ESXi hosts, a few NFS data stores. They have recently updated us of 1.5 and 5.1. For most of our committees, we have just one network of vSE/Routed that connects a subnet to a network of "WAN" and pulls a public IP address from a pool. Send us (NAT network address) and leave (firewall) ports (for example port 3389 for RDP) to the virtual machines selected. Most of these networks also have a VPN tunnel from site to site with a physical Firewall through the internet. After the upgrade, we went and converted our rules to match the period of initial and active INVESTIGATION "multiple interfaces" - effectively subtracts to compatibility mode. Everything was going well (even for devices of vSE always in compatibility mode)

  Question: We first noticed this, when a customer reported that they are unable to access a virtual machine via RDP using it is internal (protected VSE) IP through a VPN tunnel but could access the virtual machine via RDP using its public hostname/IP address. Allow us all traffic between the VPN (firewall has a whole: a rule for VPN traffic). When we connected to troubleshoot (just thinking that the VPN was down), we found that we could connect to any port on the computer through the VPN tunnel except 3389remote virtual. I can ping from the local subnet to the VM troubled on the VAPP network without problem. I was able to connect to other ports that have been opened on the remote virtual machine without problem. I couldn't connect to 3389 through the VPN.

  We thought he could be isolated, but found the question on each VSE we have: If there were a the DNAT rule to translate the inbound for a particular port, this port would be insensitive when traffic through the VPN tunnel that is meant to be the target of the DNAT rule.

  Someone has an idea what could be the cause?

  Looks like it is a problem experienced during the upgrade. These hidden firewall rules will not disappear until the firewall configuration is updated in some way. So go as - upgrade

  (1) upgrade VCD

  (2) update VSM

  (3) to redeploy the entry door to upgrade the edge of the gateway to version 5.1

  (4) convert the firewall rules to the new format (where firewall rules have no management interface or traffic)

  (5) to change the properties of the bridge and the multiple interface mode

  (6) change the specification of the firewall somehow, that is to add a dummy firewall and remove it, turn off, then turn on the firewall, etc..

  Which should cause the deny rule go away

• Transfer config data refnum problem

  I have problem of storage and transfer of value of refnum of configuration data.

  The value displayed using the seam of the probe to be OK, but it is not accepted as soon as a continuous run is used.

  The attachment shows what I tried.

  How the value of refnum of configuration data can be managed?

  Do not use run continuously.  It is designed for purposes of debugging, not to run your code normally.  If you need your code to continue to operate, put in a while loop (with a sort of timer loop as the function of waiting (ms), while it is not run as fast as possible and consume all your CPU time).  The use of "Continuous run" is like hitting the button run over and over, and some things reset each time you press the run button.  For example, whenever a first level VI ends, all the references he opened - queues, file references, TCP connections, etc. - are closed and become invalid.  This is what you see - whenever the VI ends, it closes the file, so well that the refnum still contains a value, that value is therefore more a reference valid to a file.  Use some time to keep your code running in a loop instead, and it will do what you want.

• Translation NAT PIX problem

  Hello everyone I have the following situation on a running 6.2.2 PIX 520

  I have three interfaces inside, outside, dmz

  on the external interface have an access list to allow icmp from the IPs behind the DMZ interface, I have the following:

  external_access_in list of access permit icmp any 1.1.1.0 255.255.255.0

  NAT (dmz) 0 1.1.1.0 255.255.255.0 0 0

  Access-group external_access_in in interface outside

  1.1.1.0 are routed over the internet, ip addresses of the foregoing allows external hosts don't ping my hosts behind the dmz interface

  I'm doing the same thing try to allow hosts behind the area demilitarized the hosts behind the inside interface to icmp ping:

  dmz_in ip access list allow a whole

  NAT (inside) 0 1.1.5.0 255.255.255.0 0 0

  Access-group dmz_in in dmz interface

  The Interior allows entering by default.

  But I have the newspaper:

  305005: no group of translation not found for icmp src dmz:1.1.1.1 dst domestic: 1.1.5.1 (type 8, code 0)

  In my view, the situation is the same thing as the ping outside the demilitarized zone.

  I have:

  ethernet0 nameif outside security0

  nameif ethernet1 inside the security100

  nameif dmz security50 ethernet2

  Could someone tell me where I'm wrong, and how to allow the demilitarized area welcomes guests inside interface to icmp ping.

  Thanks for your replies.

  When you use "nat 0" with a network after him, it does NOT work as a static/ACL combination that normally, you need to move from a lower to a higher security security interface, as you do here. With "nat 0", traffic not from higher security first interface, THEN traffic can flow from the lower security interface. In your example, the traffic should flow inside the DMZ BEFORE traffic flows from the DMZ to the inside. The reason it works with the DMZ to outside traffic is that traffic probably sank DMZ for outside already, while traffic then flows from the outside to the DMZ.

  NAT 0 is probably something I would keep away from, could the interpretations of the causes like that. IT is IS NOT THE SAME AS STATIC/ACL PAIR., although it is similar.

  I would replace your statements "nat 0" with the following:

  > static (dmz, outside) 1.1.1.0 1.1.1.0 netmask 255.255.255.0

  > static 1.1.5.0 (inside the dmz) 1.1.5.0 netmask 255.255.255.0

  You have still a static, but you translate it into himself, effectively bypassing NAT (even though it still go through the NAT process). Traffic will then be able to move back and forth without worrying. It's easier to read and follow for me too, but that's just my opinion.

• NAT in the IPSec tunnel between 2 routers x IOS (877)

  Hi all

  We have a customer with 2 x 877 routers connected to the internet. These routers are configured with an IPSec tunnel (which works fine). The question is the inbound static NAT translation problems with the tunnel - port 25 is mapped to the address inside the mail server. The existing configuration works very well for incoming mail, but prevents users from access to the direct mail server (using the private IP address) on port 25.

  Here is the Config NAT:

  nat INET_POOL netmask 255.255.255.252 IP pool

  IP nat inside source map route INET_NAT pool INET_POOL overload

  IP nat inside source static tcp 10.10.0.8 25 25 expandable

  IP nat inside source static tcp 10.10.0.8 80 80 extensible

  IP nat inside source static tcp 10.10.0.8 443 443 extensible

  IP nat inside source static tcp 10.10.0.7 1433 1433 extensible

  IP nat inside source static tcp 10.10.0.7 extensible 3389 3389

  allowed INET_NAT 1 route map

  corresponds to the IP 101

  access-list 101 deny ip 10.10.0.0 0.0.0.255 192.168.1.0 0.0.0.255

  access-list 101 permit ip 10.10.0.0 0.0.0.255 any

  On the SAA, I would setup a NAT exemption, but how do I get the same thing in the IOS?

  See you soon,.

  Take a look at this link:

• NAT 0-list of access

  NAT with NAT Timeout values 0

  A server outside the firewall starts a session on the server inside. The server stores the session via the IP address and the Source port inside this connection must remain open, but if there is no communication after the time specified in the timeout xl, it is demolished... then, outside server initiates a new session with a source port different... Once this happens several times, the service on the internal server dies.

  If I use:

  notimeout list allowed access host ip 10.10.10.4 255.255.255.255 any

  NAT (outside) 0-list of access notimeout

  As the pix don't build an xlate array, it will bypass the timeout for the xlate? Once 10.10.10.4 allows a connection to a host on the otherside of the pix, will he be able to be idle indefinitely?

  Thank you

  Of course, but you have some problems of syntax. Refer to the following:

  PIX #(config) access-list no.-Timeout allowed ip 10.10.10.1 host 172.16.1.1

  PIX #(config) nat (inside) - No.-Timeout 0 access list

  PIX #(config) conn timeout 0:0:0

  * No need for 255 mask all when you specify host. And you want to apply the NAT inside interface. Translations when using a nat ACL 0 device still can be built from the less secure interface. And your timeout on the conn will be global. I do not recommend the use of what it can cause side effects. Each conn that is left in an open incorrectly state never fade conn PIX table. This can cause memory exhaustion over time, so if you're going to do this, please check the "County conn hs' and"sh conn detail"often of output and make sure that you don't have many & open on the PIX. It may require manual intervention you clear the & or reload the PIX.

  If you are in a situation where the connection must remain open indefinetly between these machines, you may be better of the location of these two hosts on the same segment so as not to take these measures. Just a thought.
