I've a question regarding setting up a S2S vpn between a cisco 1800 and a Cisco 871 .

The cisco 1800 is the "corporate" hub and the 871 is installed in the branch.

The 1800 has already been configured as Easy Vpn Server for remote access ( vpn clients ) .

Now I need to add a S2S VPN with the branch office.

The first question is about the aupport for such configuration . I remember to have read , if I'm not wrong , that Easy VPN can be set up with only 1 IPSEC tunnel . Is it right ? Do I need to rebuild the configuration from scrath ?

The second question is about examples ( where can I find some ) .

Thanks all for the help
