Cisco PIX to PIX VPN issue

Mar 19, 2008 1 Replies

I have a client with two locations that I'm setting up a a point-to- point VPN. The tunnel was up and idle earlier today, it's nonexistant now, and I'm out of ideas.. At no time was I able to ping across the PIX's.



Pix #1 also has a VPN config for remote clients that works fine.



Here's pertinent info from each configs:

According to my directions from the Cisco site, it looks like I have everything I need. The tunnel was up when I did a show crypto isakmp sa earlier today, but now it's not showing in the list. My brain is fried, and I need a little help. Can someone help shed some light on what I've done wrong?

As you say that it was working..just try changing the pre-shared key on both the peers. You could check what the the status of the tunnel and try doing a debug

show crypto isakmp sa debug crypto isakmp debug crypto ipsec

paste the output over here, if it still has issues.

thanks
