We are currently using the GRE Tunneling that comes with the routers to several subnets, because it is so incredibly fast and easy to set up. We would like to move to IPSEC and throw in some encryption, but I cannot find any configuration samples for multiple sites that connect to a single router(i.e. HQ and multiple Branch Office scenerio).
I think I need a seperate Crypto Map for each tunnel, but can I use the same isakmp policy / transform-set / ?
We have Cisco 1700 Series Modular routers, with IOS12.2
Any help / how-to's are appreciated,
Paul
