Firewall drops traffic
I have a problem with a VPN 100 appliance here. It's set up as a VPN endpoint for users, as well as 2 other branch offices.
The VPN is working fine, as far as I can tell, but some computers at the main site get their outgoing traffic dropped by the firewall. This applies only to WAN traffic. LAN is working fine.
The device is set up behind a primary router with the VPN 100 as an exposed host. All devices are in the same subnet 192.168.11.x
WAN is 11.8 with GW 11.1 and LAN is 11.7. The clients use 11.7 as the GW. The physical ports are in LAN1.
The policies look as follows:
By my understanding this should work. Why do some clients get this?
What am I overlooking? Can anyone help?
P.S.: Funny enough, some clients can access the internet after pinging the WAN and LAN IP of the VPN 100. 🤔
