506th PIX, no NAT configuration?

Similar Questions

• My 506th Pix configuration

  How can I set up the following scenario. My Pix is separate internal and external network. For outgoing, I will not allow that the associated HTTP traffic. There will be no incoming traffic. For simplicity, I use ver3 PDM to configure my 506th Pix. Should be easy to set up, I thought.

  On my access rules, I allowed http and https on the inside and outside interfaces nameserver. Translation rules, I have set up NAT using a real IP on the external interface range. I have not used just in case PAT H323.

  However, the configuration above does not work. I can't any http my internal network traffic. What Miss me?

  Thanks for your help,

  FTM

  It would seem that you define the rules that indicate the source AND destination must be the same:

  inside_access_in list of access permit udp any eq field any eq field

  inside_access_in list access permit udp any eq ntp ntp any eq

  inside_access_in list access permit udp any eq name server any eq nameserver

  inside_access_in tcp allowed access list any domain eq any eq field

  inside_access_in tcp allowed access list all eq www all eq www

  inside_access_in list of permitted tcp access any https eq all https eq

  You need change that, because the source is probably going to be 1024 or greater. Try something like this:

  inside_access_in list of access permit udp any any eq field

  inside_access_in list of access permit udp any any eq ntp

  inside_access_in list access permit udp any any eq name server

  inside_access_in list access permit tcp any any eq field

  inside_access_in list access permit tcp any any eq www

  inside_access_in tcp allowed access list everything all https eq

  inside_access_in access to the interface inside group

  Having said that allow any source ip/source port access to any IP destination as long as it is for www, dns, ssl, etc...

  Your acl_web access list is not used, because it is not assigned to an interface. Remember that each interface can have only one acl.

  Also, you said that you do not PAT...

  Global (outside) 1 xxx.xxx.YYY.54 - xxx.xxx.YYY.55 netmask 255.255.255.0

  Global 1 xxx.xxx.YYY.53 (outside)

  NAT (inside) 1 0.0.0.0 0.0.0.0 0 0

  This tells the firewall to use the range xxx.xxx.YYY.54 - xxx.xxx.YYY.55 for the assignment of an address, but when he runs, start PAT'ng with xxx.xxx.YYY.53...

  hope this helps

• PAT on PIX vs NAT overload on router

  Better question practice...

  It's better to perform PAT through a NAT overload on a router bastion with a static on the PIX instruction or PAT on the PIX configuration uses a global IP address?

  Other alternatives?

  Example of router *.

  Router configuration

  IP nat FirstPAT 172.16.5.100 pool 172.16.5.100 255.255.255.0

  FirstPAT IP nat source list 10 overload

  access-list 10 permit 10.10.10.0 0.255.255.255

  PIX installation

  static (inside, outside) 10.10.10.0 10.10.10.0 netmask 255.255.255.0

  Example of PIX *.

  Global (Outside) 1 172.16.5.100

  NAT (inside) 1 0 0

  Thanks in advance for all the messages!

  In my opinion, there is no real compelling reasons to go with one idea on the other. Probably, I would lean towards leaving the PIX do NAT, but I could be swayed. The reason is that the PIX has essentially already been NAT (all back on the same address). But again, either should be good.

  A suggestion however if you went with overloading NAT on the router would be to do it with a map of the route as opposed to the example of access list you have. Something like this:

  IP nat FirstPAT 172.16.5.100 pool 172.16.5.100 255.255.255.0

  IP nat source map route nat FirstPAT overload

  route nat allowed 10 map

  access-list 10 permit 10.10.10.0 0.255.255.255

  This creates a NAT entry in the NAT table on the router.

  Good luck.

  Hello

  I went through the ongoing discussion. The pix configuration should be fine for now according to suggestions. The problems seems to be on the server. If it is a new installation of windows, then there is an option not to accept requests that are not local network.

  If you want to check if pix allows connections and then when you telnet to port 25 of the outside, just run the xlates control.

  SH xlate and it should show you a translation for the inside host. More than a quick test if pix allows traffic is to check 'sho-outdoor access list' and see if the counters are increasing.

  Hopefully this should help you.

• Intercommunication 506th PIX VPN to VPN windows server

  Most of he says title.

  I got a 831, and I only needed to port before the pptp tcp port 1723 to my Windows 2003 VPN server.

  Got 506th pix until 2 days ago and I cannot find a way to pass traffic. Obviously tcp 1723 is mapped statically. And I checked this command for accuracy.

  Configuration mode, enter the following command:

• 506TH PIX

  I have a 506th pix that I couldn't connect this morning. I had a user restart it for me while I did a ping t on this subject, the ping of the ip address of the element has disappeared, and the ip address of the proxy server now rises. What would cause this

  pings from the hosts or routers to the PIX firewall interfaces fail, check the debugging messages, which must be displayed on the console. Ping successful debugging messages appear as in this example.

  ICMP echo reply (len 32 id seq 1 256) 209.165.201.1 > 209.165.201.2

  Application of echo ICMP (len 32 id 1 seq 512) 209.165.201.2 > 209.165.201.1

  Statements of the request and the answer should appear, which shows that the PIX Firewall and the host responded. If none of these messages appeared while ping interfaces, then there is a routing problem between the host or router and the PIX firewall that caused ping (ICMP) packets to never get to the PIX firewall.

• Telnet Session 506th PIX

  I have a problem with my 506th Pix: I can not connect by telnet session. Y at - it an option to reactivate PDM?

  Thks

  Yes, there is a way to access Telnet via - PDM

  Cofniguration-> system-> Administration properties-> Telnet

  Here you can add the host IPs you can telnet and specify the interface where these customers.

  Note: You cannot telnet to the outside interface security PIX firewall / low level.

  Kind regards

  Hi Burns I had the same problem, you need to do is to go to www.java.com and download the java applet and try and access the PIX will work without problem

• PIX and NAT - T

  Hi all

  I have a small question. I have a couple of users who use routers to connect by VPN to our pix that authenticates by a RAY for L2TP connections. I enabled the NAT - T on our PIX and they may not always connect. Is there anything I might have missed. I checked most of the posts in this forum do not see anything else, I should have activated.

  Can anyone help?

  Thanks in advance.

  Michael

  A tunnel of Lan-to-Lan of a router in a PIX does not NAT - T, unless there is NAT devices between two end points. If this is the case, you must ensure that both the software both from the end of rehbeh points devices support this capability. An example of a router to tunnel PIX IPSec configuration is available at http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094498.shtml

  Another example that deals with the same configuration with NAT is available at

  http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a0080094a87.shtml

• PIX SMTP NAT or Port based NAT?

  I have what may seem like a strange question...

  I have a client with a PIX and a SMTP server inside their network. They were using a NAT Port basis via the following command (all IP addresses are changed to protect the innocent):

  static (inside, outside) 1.1.1.1 tcp smtp 192.168.0.1 netmask 255.255.255.255 smtp

  It worked well for incoming and outgoing email except to go to particular mail servers. What was going on, it was that they were receiving messages from rebound as below:

  Where IP address 1.1.1.2 combined with overall command of the client.

  Once I changed the nat to use a normal NAT rather than on a port a whole worked well. Download

  static (inside, outside) 1.1.1.1 192.168.0.1 netmask 255.255.255.255

  My question is can I do nat based on the port works for IP addressing in the two directions or am I stuck with the help of a single IP NAT?

  I guess what is happening, is that the NAT based on the port looks only to conversations from the incoming direction (ie the conversation is with port 25 on 192.168.0.1), no conversations from the outgoing direction (ie the conversation is with port 25 on an external IP address).

  Rgds,

  Peter

  Excellent analysis and you are immediately. Just a simple set-config that lack of most people. Try the following:

  static (inside, outside) 1.1.1.1 tcp smtp 192.168.0.1 netmask 255.255.255.255 smtp

  Global 2 1.1.1.1 (outside)

  NAT (inside) 2 192.168.0.1 255.255.255.255

  The static method will match the traffic from port 25 to the mail server. So when your mail server sends outgoing traffic on one port other that the 25, he uses the nat/global configuration you have defined for the other hosts on the inside interface. Who obviously doesn't like the other e-mail server.

  Hope that's clear, but if not, let me know.

• Help with customer 501 pix for the configuration of a site...

  Hello everyone, I am trying to set up a customer vpn site and after a few days

  I'm at the end of the roll.

  I'd appreciate ANY help or trick here.

  I tried to set up the config via CLI and PDM, all to nothing does not.

  Although the VPN client log shows the invalid password, I am convinced that the groupname password is correct.

  Mmmm... What version of vpn client do you use?

  If you use the last being, it looks like you might have it downgrade to a version older than the version of your PIX is old enough.

• Global PIX and nat settings

  My PIX configuration has two world and two nat settings.

  Global (outside) 1 65.209.4.220 - 65.209.4.253 255.255.255.192 subnet mask

  Global (1 65.209.4.254 255.255.255.192 subnet mask outside)

  NAT (inside) 1 0.0.0.0 0.0.0.0 0 0

  NAT (intf2) 1 0.0.0.0 0.0.0.0 0 0

  I can understand the two commands of nat, more or less, but I can't understand why the two global commands and what they do. Can someone clarify the situation?

  Oh I should have read your question more carefully. The 1st World allocates addresses for guests inside and intf2.

  Once the pool is not the address, then it will use the 2nd global and it will now start making Polo and non-originating, as was the case in the 1st world.

  So, indeed, until all the addresses in the global pool are exhausted, all of these hosts will be coordinated. After that, the new hosts come out will be PATed with the adresse.254.

  Hope it clears.

  Thank you

• 506th PIX and VPN client - multiple connections connections

  I have a PIX of the 506th (6.2) w/3DES license and 3.6.3 VPN client software. I'm only using group user name and password to authenticate. The first user login works fine. When the second user connects, the first is finished and the second works very well. The product turned on States I should be able to have 25 simultaneous connections or site to site or customer.

  Any help will be greatly appreciated, Kyle

  Are these two users on the same site, behind a device that makes PAT? If so, then this device is causing the problem, not the PIX. The device is unable to correctly translate the IPsec packets. Unfortunately nothing you can do about it on the PIX, although the next version of the software (6.3 to your calendar of March) will have NAT - T support (which the client currently supports). Once that support NAT - T both ends, they'll be able to say that there's a PAT instrument between the two and they will automatically encapsulate everything in the UDP packets, which your PAT instrument will be able to translate correctly.

• 506th PIX IPSEC VPN allow authentication for local users?

  We have a 6.3 (5) running PIX 506th, configured for Cisco's VPN IPSEC clients. Cisco VPN clients authenticate with the credentials of group fine, but is it possible to use local users to authenicate plu? We use local users to our existing PPTP VPN clients, but we want to migrate these users to IPSEC. Any info would be greatly appreicated.

  Of course, you can... you need to include the command on your card crypto below

  map LOCAL crypto client authentication

  I hope this helps... Please, write it down if she does!

• 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.
