Outbound Traffic

Post by gikuxayi »

I have read information on firewall configuration for Transmission-Daemon and it appears all is working but I have quite a lot of denied firewall outbound traffic. I am able to download torrents from a specific tracker I am allowed to access and when viewing the peer listening port in the GUI it shows open. Also if I go to canyousee.com it is successful on the chosen port. I am hoping someone could advise if I have a configuration issue and confirm what traffic should be permitted for proper function. Thanks!

OPNSense Config:

Destination NAT:
WAN Interface: TCP/UDP Src: Any Dst: WAN_IP Port 55555 > DebianIP Port 55555

Firewall Rules:

LAN Interface:
TCP/UDP Src Any Dst Any Port 53,123
TCP/UDP Src Any Dst tracker_url Port 2145
TCP/UDP Src Any Dst portcheck.transmissionbt.com Port 80
**** Implicit Deny All ****

WAN Interface:
TCP/UDP Src Any Dst DebianIP Port 55555
**** Implicit Deny All ****

Firewall Logs show a multitude of entries like the one line shown below (with the real IPs and ports omitted). I believe the firewall should be stateful and handling this return traffic? Any help or ideas are appreciated. I do see some peers leeching from me, not much.

Src DebianIP:55555 > RandomPublicIP:RandomPort Default Deny (Blocked)
