I have configured tunnel for both routers the RV042G says the connected. However, I am not able to ping via ip or anything else.  Both routers are connected to main location via tunnel. That connection is the same and is working. I have checked everything that I can with no luck.

Site B: RV042G (10.2.X.X)
Site C: ASA5505 (10.20.X.X)

Both are connect to site A (ASA5510) with no problem.

The first and obvious check here is to ensure each end has an internal subnet address and not just a single IP. The latter will prevent any pinging of other internal addresses.

I have site to site tunnels with an RV325 VPN router so these boxes fundamentally work.

What exactly are you trying to do? A ping from B to C? Are these Site-2-Site tunnels (without using NAT inside the tunnel)?

they both have subnets declared. without that there would be no connection. I need sites B and C to be able to communicate. They are setup site to site with Nat on the ASA.

Make sure Mode is set to Main and not Aggressive.
Try setting NAT Traversal ON. Try it both ways.

Post the configuration of one end (start with the RV042G).

I'm no Cisco'si, but I know ASAs require special configurations for hair-pinning VPN connections (allowing interesting traffic to cross tunnels). That you apply NAT inside of the tunnel might make it more difficult than required. too.

This has been resolved. I had to verify and make some changes to the ASA device.
