VPN default route question

I have two Cisco 1721's configured to connect to the internet via a cable modem.  The 1721's are also configured with a VPN between them.

Simple config is as follows -
(I used easy numbers to make this simple)

Router A:
public IP 11.11.11.11 on E0
unnumbered VPN through E0 to Router B
Private IP on F0 192.168.1.1

Router B:
public IP 22.22.22.22 on E0
unnumbered VPN through E0 to Router A
Private IP on F0 192.168.2.1

On Router B network there another router, call it Router C that is connected to 192.168.3.0 via it's F0 of 192.168.2.2.

I want to put a static route on Router A for the network attached to Router C.  The statement is something like -

ip route 192.168.3.0 255.255.255.0 ?????????????

The question marks are what I do not know.  The route goes through the VPN to get to the other network so that is why I do not know what the gateway should be.

Any comments are appreciated.

Thanks.

Depends on how you have your VPN's set up. Using IPSEC with ACL's, simply add the 192.168.3.0 0.255.255.255 subnet that triggers the VPN, and forward to the other router.
Your VPN router A should have some statement that says basically, any traffic matching acl #, send to peer router via encrypted tunnel.
The router at B will also need to have the network of C added to the traffic that is returned to A via the tunnel.
There is no route statement needed unless you are using GRE tunnels with encryption.
