Pix 501 - Site-to-Site VPN Tunnel

Hello NG

I hav now tried multiply times to create a site to site vpn tunnel,
between 2 cisco pix 501 firewalls

I have tried through GUI and CLI. I have even used cisco's own
configuration guide. but without any luck.

Anyone that have a solution, please reply

~Peter

 

x-no-archive: yes

With out the configs it is impossible to tell what you are doing wrong.

Are the tunnel being formed but no traffic passed?


Is the IKEA negation successful?


Peter ?

to check
1st command) sh isakmp sa
2nd xommand sh ipsec sa

 

Don't use the same ACL for two different purposes (e.g., nat 0 and
crypto map). There are some situations where it is promised that
it definitely will not work, and there are some situations where it
simply doesn't work properly.

It isn't worth your time trying to track down the cases that work
without bugs, seeing as that might change in the next subrelease.
