hi
I have stood up a site to site VPN link between a Cisco SA520 and a Cisco SA540 using a single VPN and IKE profile.

I can get IP routing between the branch office and the subnet included in the VPN profile.  ie, 10.80.30.0 to 10.3.0.0. All works.

However, i can't seem to add routes to other subnets in the main site.

When i add the route using the networking tool, the PING appears to travel via the interent and not the VPN tunnel

both routers are on latest firmware.

Do I need to create separate VPN profiles for each subnet I need to transverse via the VPN tunnel?

You need to include the IP range in the access-list called in the crypto map. You also need to exclude that subnet from NAT

Hi Akinsd, I am not sure I can do that using the Cisco SA540 Web interface. Normally I am used to using ASA's

I use ASAs myself via command line.
You may try this manual

I saw a picture in page 20 "Review VPN policy created by wizard"

Somehow somewhere, there should be an area where you would exclude interesting traffic from NAT and include in the ACL used in the policy
