Hi! I have a problem with routing traffiic between two VPNs. At one company (Location A) has two VPN connection, with location B and location C. I would like to route traffic that comes from location B to location A thru our router (Draytek Vigor 3300) to location C. Local IP at location A: 195.246.21.0/24 (they are using those IPs as PRIVATE IPs) Local IP at location B: 10.251.11.0/24 Local IP at location C: 192.168.13.0/24 I'm in the process to change IPs at location A to standard private IP range (192.168.12.0/24). My problem is how to set static route at my Router that traffic will go from B, trhu A, to C. Any suggestion? Thx, Uros.

Not familiar with your router. But since your hub and spoke VPN is probably working. All you have to do is set the IP route at Site B. At site B, set an IP Route for packets going to 192.168.13.0/24 to route to Site A. Once the packets are in site A, you already have a route that will send the packets to site C. You will have to set the same thing on site C so packets can get back to Site B.

    Not keen to thay type of router, but in CiscoLand, this can be accomplished by using Dynamic Multipoint VPN's. Basically, you are setting up mGRE tunnels, and if you want IPSEC, and the hub router keeps a database of the connections, by using next-hop resolution protocol or NHRP. Router C and Rouer B I assume do not have each other's inside networks in their IPSEC interesting traffic ACL's, so how will traffic be encrypted from B to C or C to B through A? There needs to be some sort of mechanism in place to control traffic beyond static routes.
