I have a Linksys AG041 ADSL router (available in Europe and Australia only I think) attached via a VPN to a Linksys RV082 in our central office. The private NAT addresses are 192.168.101.2 and 192.168.121.250 respectively. I have set up the VPN and devices on both networks can see each other through the tunnel.
The 192.168.121 central office network is a hub with a number of other networks connected via leased lines and isdn. Another router (a Cisco) at 192.168.121.254 handles these connections - for example to 192.168.106.N.
My question is how do I set up my Linksys routers so that traffic from my 192.168.101 network can route via VPN to 192.168.121.250 then to 192.168.121.254 to get to 192.168.106.N? I already have a static route set up in the 192.168.121.254 router and I can ping it from 192.168.101.N. I have tried but I can't work out the static routes etc to make it go any further. Has anyone out there done something similar and would like to share how it's done? I have attempted a simple diagram below.
Thanks and regards
