Solved: IPSec VPN between PIX and Cisco 877W

pvzcisco07 · ‎10-31-2007

Hi All,

I am trying to create a VPN tunnel between a PIX and a Cisco 877W but cant seem to get the tunnel up. When I do a 'sho crypto session' on the Cisco 877, I get it said status of session was down, then changed to DOWN-NEGOTIATING, but it is now DOWN again...Please find attached configs for both ends...Are there any commands to confirm that the tunnel is up other than trying to ping the remote end? I would greatly appreciate any help to get this tunnel up.

Regards,

Raj

Hi,

Based on the attached configurations, there needs to be couple of changes made. For example:

1. The isakmp policies do not match on the router and pix. Make sure that the Hash, DH Group and Lifetime match on the 877 and pix.

2. The access-list for the ipsec traffic has to be mirror images of each other.

3. Make sure that the ipsec lifetime matches on both the peers.

I hope it helps.
