I have two networks:
Network A Private 10.0.0.0/24
Network B Private 10.0.10.0/24
Both running Sonicwall ~200 appliances, connected by a VPN tunnel.
I am able to reach specific internal address on either end of the tunnel from either location, works like a charm.
What I would like to do is route all web traffic to a specific domain (whatismyip.com, for example) such that:
When someone on network A attempts to access the website whatismyip.com the request is routed over the VPN to Network B using Network B's public IP address.
When someone on network B attempts to access the site, it should come from Network B's public IP as normal.
I've tried accomplishing this using Sonicwall Route rules, but it's not working as I expected. I'm at a loss at where to begin, really.
What is the outline of rule (Firewall / Nat / VPN / Route) configuration necessary to accomplish this?
