VPN & PAT

mhcnetadmin · ‎01-24-2008

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.
