Have a server on the LAN network that has a permanent VPN out connection for internet. I can reach this server locally from the LAN network, but despite having firewall rules, cannot communicate to this server from another VLAN when the VPN connection is active. What do I need to add to make this work? Any help would be appreciated.
Looks like this VPN connection is binding the default gateway, so all traffic which doesn´t has a static route is going to that VPN tunnel. You can either disable the VPN binding the default gateway or add static routes to the server to other LANs
Going to Firewall, Settings, Advanced and enabled Reflection for port forwards and Automatic outbound NAT for Reflection resolved my issue.
What does your solution has to do with the problem you reported? Can´t see a correlation between them. There should be no NAT in use from what you described.
