response from incoming traffic is going out through the default route

[redstang33]

Hi,

I'm using this exact setup with pfsense, PIA, and transmission. However I find that the replies to the incoming connection requests are gonig out through the default route. To be exact:

• I can see the SYN requests for incoming connection requests come in through the VPN interface.
• The SYN/ACK response is going out through my default route though which is the WAN interface.

I saw that there were bug reports for pfsense 2.5.1 with this problem but they claim it's fixed in 2.5.2? I am using pfsense 2.5.2.

never mind. After lots of googling I found this: https://forum.netgate.com/topic/168647/inbound-openvpn-port-forward-no-response/4 ... It seems that having an OpenVPN server at the same time creates a firewall route to a group OpenVPN which influences the reply-to of the client. Case closed and the script is working fine!
