ANSWERED How can I use AirVPN port forwarding over a VPN Opnsense interface.

[repok21 0]

I currently have a AirVPN VPN interface on my Opnsense firewall with my torrent client device correctly routing through the virtual VPN interface. Everything is working except port forwarding. When I ran the OpenVPN client on the torrent machine itself using the OpenVPN client, the port forwarding works. When I route my torrent machine through Opnsense and the virtual gateway (with proper port forwarding rules) then it does not work. Nothing is being blocked at the firewall and when I run
sudo tcpdump -i enp2s0 port 62524 -n

it shows connections between my torrent machine and external public IPs on that designated listening port so Im a  bit confused. Something isnt working because upload speeds are extremely slow and the port forward test fails on the airvpn page. Here is output, am i going crazy?

tangodown@seedbox:~$ sudo tcpdump -i enp2s0 port 62524 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on enp2s0, link-type EN10MB (Ethernet), capture size 262144 bytes

EDIT: Fixed the issue. under the Firewall -> Rules for both the floating and the VPN interface rules, i had to set the 'reply-to' to the AirVPN gateway
