we currently have an ethernet link between two sites and a tunnel between the sites as well. However, we also have a route inside command on the firewall (506e) to send traffic directed to the other site to the router where the ethernet link terminated. we have it because the pix uses ACS and the server is located at the other site. The router also knows about the subnets on the other side through eigrp.

Now I was thinking about adding some static routes on the 506e as such:

route outside 10.0.0.0 255.255.252.0 82.141.x.x 200

route outside 10.20.0.0 255.255.0.0 82.141.x.x 200

Thanks,
