I have a 2040 pro enhanced.
When I initially setup my WAN Group VPN I had 1 ISP on the primay WAN port (X1) and every thing worked fine.

I have a new ISP on my Primary port X1 and moved my previous ISP to X2 and have the ISP's setup in a basic active/passive failover mode (if that matters).

Anyway, I have never been able to get the Global VPN client to connect via X1 on my new ISP. I can still connect via X2 which is on my old ISP.
When I try to connect to X1 the client just hangs forever trying to connect, and my firewall log shows this error for the IP I am trying to connect from:
"Alert Intrusion Prevention IP spoof dropped"

Log of denied connection attempt on X1:
