I need to be able to create an IPsec site-to-site VPN with either a 2600 or a 3600. Niether of the routers I have seem to support it with the version of IOS they are running. Can I download a version that does or do I need to buy it from Cisco. Could someone point me in the right direction?
You need IOS that support crypto. I guess both your routers don't have enough memory. It would also recommended that both routers have AIM-VPN cards or you'll sacrifice CPU for the encryption. Finally, how many VPN tunnels do you have in mind and what throughput are you designing?
