I have a strange problem that I have been fighting.
Site A - internal network 172.31.16.0/24
Site B - Internal Network 172.31.17.0/24
Site C - Internal Network 10.0.0.0 /8
I have vpn tunnels connected from Site A to each site. Sites A & C can talk to each other. I cannot get the traffic from Site B to talk to Site C.
Attached is my config.
The VPN tunnels are up and working.
