OpenVPN server community version behind Endian Firewall not able to bridge

[Guest]

Newbie here....

Setup standalone OpenVPN server separate from Endian Firewall.

EFW community runs on physical server hardware.

OpenVPN installed onto CentOS7 OS Virtual Machine runs on a Windows Server 2012 R2 HyperV.

We NAT port 1194 to OpenVPN server.

Clients successfully hit OpenVPN server, but cannot see network behind the OpenVPN server.  The OpenVPN server not bridging as needed.

I changed all OpenVPN settings/configuration I could think of.

Is there some settings in EFW that I need to be aware of?

Thank you for your help.

If you don't NAT the VPN clients on the Centos 7 VM I think you need from the endian side to add a routing rule that tell to the systems in LAN or DMZ how to reply back to the VPN clients.
You can check if it's a routing problem with tcpdump on Centos 7, if this is the case you should see the traffic exit from the ethernet interface but doesn't come back.
Why you are not using the OpenVPN on the efw?
