    Here is the situation:-

    I have a gateway to gateway VPN Tunnel connected with a RV082 on one side and an unknown device on the other. The Tunnel shows "Connected" as the status on the router. The remote subnet is The Local LAN subnet behind RV082 is

    I want to have some clients connect through the tunnel to the remote LAN. Is this possible? Am i missing some routing rules?

    That's pretty much how it's supposed to work. The RV082 will make itself the default gateway for all destination P = traffic that's coming from the internal network ( in your case) IP clients on the subnet should be able to ping into the subnet. NetBIOS does *not* pass in these tunnels by default so you might have a bit of trouble browsing file and print share in the tunnel, especially if the "unknown" device doesn't permit NetBIOS broadcasts in the tunnel. We're also hoping that it *knows* how to route the traffic back to your RV082 for the replies, etc.

    Perhaps you could be a bit more specific as to what your problem is and I'm sure that I (or someone else) would be glad to help you!

    Have you got Breezy! ?

    Thanks Eric!! I think you understand the problem right away.

    This is my first problem. After the tunnel is setup, I need to setup some SIP endpoints and connect over VPN to the remote LAN which has the server the endpoints need to register with.

    Not to be dense...but are you actually having a problem or are you just trying to get your mind around how it works? Seems to me that what you're doing is quite simple. As long as the VoIP adapters can see the server through the tunnel then everything should work fine. I'd worry a bit about QoS, though unless the tunnel is dedicated just for the VoIP stuff.

    It is my first time setting up this kind of configuration. I agree that this is simple setup but I am new to VPN. I am worried about bandwidth over the VPN tunnel even if I get this setup working. The reason being the SIP end points are being tested for video calls.

    Finally I found out the other end is a RV016 and the person who is configuring on the other end being a nutcase. Thanks for all the help! I really do appreciate it.

    Thanks for the update. Let us know how it works out! /Eric

    Eric, Thanks for the information. The setup is working. In the process a bug was found on the SIP endpoint (Static IP did not allow classless routing) and MTU setting was synchronized (don't know whether that was the cause for failure). But as you said, in retrospect (for me) it looks a pretty straightforward configuration.
