IPsec VPN on RV042 Question

Answered Question
Aug 16th, 2012
User Badges:

I have two routers, A and B, which have a VPN between them (across the internet).  If my understanding of VPNs is correct, then traffic should only be routed acorss the VPN tunnel when a client on the Router A LAN is trying to reach a client or resource on the Router B LAN, or vice-versa, correct?


Traffic destined for a resource outside either of the LANs should be routed out the WAN of the router, correct?


I ask this question because I have programs (which access the internet) that are behaving badly when the VPN tunnel is enabled between the two routers.  When the tunnel is not enabled, there are no problems.

Hello Matt, when using a site to site tunnel between RV0XX router, it is a "split tunnel". The router is supposed to support wildcard masking (full tunnel) however that is a different configuration.


With that being said, your normal traffic flow is as described. Local traffic from Source A requesting local traffic at Destination B will use the tunnel, but internet traffic local to either router will be local to the respective location.
