[SOLVED] Port Forwarding with OpenVPN Client (FW Rule Issue)

[glego]

So I'm trying to set up some services behind an OpenVPN Client Host.

So far I can see in Wireshark that the packages are reaching the receiver but can't complete.

My Configuration

• Interfaces
    WAN
    LAN
    VLAN1
    OVPN (none/none)

• NAT Port FWD
    Interface: OVPN
    Protocol: TCP/UDP
    Destination: OVPN Addresses
    Port Range: 27687
    Redirect IP: MyHostOnVlan1
    Redirect Port: 27687

• NAT Outbound
  Interface: OVPN
  Protocol: Any
  Source: MyHostsOnVlan1 Subnet

• Firewall Rules VLAN 1
    Source: MyHostsOnVlan1 Subnet
    Dest: Any
    Gateway: OVPN

• Firewall Rules OVPN
    Source: Any
    Destination: MyHostOnVlan1
    Port: 27687

• Firewall OpenVPN
  Source: Any
  Destination: Any

When I check the states I get

Interface: OVPN / TCP external:54270 -> MyHostOnVlan1:27687 (MyOpenVPNIP:27687) SYN_SENT:ESTABLISHED
Interface: VLAN 1 / TCP external:54270 -> MyHostOnVlan1:27687 ESTABLISHED:SYN_SENT

Thanks for your time!

Make sure the inbound traffic is NOT matched by rules on the OpenVPN tab (disable all rules there) and IS matched by rules on the OVPN tab. That will get reply-to functioning.

Removing the rules from the OpenVPN tab resolved the issue. Thanks!
