VPN & PAT

Hi all

I configured PAT rule so that the vpn traffic from a remote client is forwarded through cisco 2821 router to vpn box (Nortel contivity) the problem is that when IKE traffic received the router forwarded to the client but somehow missing I mean that the vpn box waits to ISAKMP proposal to come but nothing arrives, and the connection is terminated. Here are the rules

ip nat inside source static udp vpn_box_address 500 interface wan_interface 500 ( this is for IKE)

ip nat inside source static esp vpn_box_address interface wan_interface

I have configured access list to allow the traffic

Any idea?

Add GRE and AHP for your PAT and that should take care of it.

you mean to the access list, because in PAT rules all I can add is esp,tcp,udp nothing else !!

the problem is solved the routing in the vpn box was wrong, thanks
