As well as FW IOS you need IPSec 3DES feature set. Although you could set up
IPSec with DES I would not recommend using it across the Internet.
IPSec does not support broadcast or multicast traffic passing through the
tunnel so if you require this (OSPF etc.) you need to use GRE over IPSec.
There's lots of information on www.cisco.com including sample
configurations.

Hi,
Please can I hear peoples views on the following:
I want to connect three sites together via the internet. (I just made this
up)
I have FW IOS feature set routers .
what are the pros and cons of implementing
1. native IPSEC
2. IPSEC over GRE tunnels
3. IPsec using VPDN peering beyween routers.
cheers
