Cannot reach IP through a VPN. NSA 2650 & TZ670


Got an interesting situation that I would love your advice on…

Site A – SonicWall NSA 2460


Secondary router from a DMS company at that VPN routes to (their DMS system)

Site B – SonicWall TZ670


I have a VPN tunnel that connects all subnets via static routes and I can ping back and forth through the VPN tunnel, including the DMS router on site A. My issue is that I cannot reach their DMS system from Site B through the VPN tunnel. I am sure I am missing something?

I tried to create a static route to from Site B but because I cannot ping it, the route doesn’t work,

    Let me clarify a bit because as i have gone through this, i see where the issue may be.

    Site A, and

    VPN Tunnel to Site B

    Each side is routed back and forth and i can ping all subnets both ways

    The issue is that site A has a vendor's router ( that has a VPN to

    My challenge is i cannot reach from site B - the vendor's router NATs from to and has a route back to site B

    Thanks for any help you all can add

    Site B went straight out to the internet and not through the VPN

    Site A did not go through the SonicWall and when straight to the vendor's router
