Routing and VPNs

By kylej6 ·

I have two buildings that are connected to the internet, one has a Cisco 1841 router, and the other a Cisco 871 router. They are linked with an IPSec site to site VPN. I have just finished installing a content filter at the site with the 1841 router.

My goal is to have the router be able to set up the tunnel, route all traffic through the tunnel by default, but route all traffic out the dialer0 interface if the tunnel is down.

Is it just as simple as adding the ports I want forwarded through the VPN tunnel to the IPSec ACL and denying in the NAT ACL?

Thanks in advance.
