Cisco 2600 VPN point to point problem.
Hi all,
I’m trying to set up VPN ptp between Cisco 2600 router and PIX 501. I know PIX 501 quite well so I’m sure is set up correctly. However Cisco 2600 is for me black magic.....
I found some documents with advanced configuration and following steps wasn’t able to establish tunnel. Could you help me and give any link with basic set up please? I need something very clear which will be suitable for my Cisco router knowledge.
Many thanks.

Optionswastedtime Member Posts: 586 ■■■■□□□□□□I just going to take a stab at this. It looks like you may be Nating your VPN traffic. Make sure you exclude your VPN traffic from the Nat traffic. Also I would double/triple check you got phase one and two the same for both devices. Other then that I would just check your debugs/show commands which are listed in this link along with a nat example.
