Re: LAN-to-LAN Tunnel between VPN 3000 and Cisco 1721
What is the ping time difference with/without encryption? You might be having another problem. You have a vpn router with accelerator card and you are doing vpn, why wouldnt you be using encryption in this scenario? I guess if its not an issue, you can always go with just gre, if its R2R. There will be some overhead with ipsec, but it shouldnt be a huge difference. Try running a debug ip icmp and do your ping test as well. Maybe even try sending a file, with encryption. This will give us a clue whether or not your experiencing a mtu issue which is quite typical with ipsec. 12.2.11T for ipsec, bleh. But that can be addressed later.
