We have an IPsec VPN between FortiGate 60E and SonicWall NSA 2600. The VPN is up and active but no traffic is passing across it.

What does your routing table look like?

Yes, phase 1 and 2 are up. Already verified that beforehand and verified again

Did you at least do "diag debug flow" ? It will tell you everything that is wrong or what's happening.

You have to help us in order to help you.

Also patterson mention traceroute earlier. I would also add "diag sniffer packet" and select the tunnel interface name that you use in phase1 and witness the traceroute enter/exit the tunnel

That would confirm traffic in the tunnel assuming a route-based and you run traceroutes from A and Z sides.
