Title: I can't get port forwarding to work
Post by: Nnyan on August 30, 2021, 12:22:04 am

Hello all,

So I'm following this guide here:  https://forum.opnsense.org/index.php?topic=8783.0  and I've tried a few others that just had some settings differences from the guide above.

So any of the external scans just show the port as being blocked or filtered and my internal app never gets the port forward requests.  To isolate the issue I dusted off my Unifi USG and Palo Alto PA-220 and after a bit of updating and configuration plugging them in allows the port forward to work (scans show it to be open and my application gets the requests). 

Looking at the firewall logs are a bit hard to understand but I don't clearly see what/where it's being blocked.  If I filter it to show port 32400 I see traffic being allowed (second screenshot) but it's not on the WAN side.  Any help figuring this out will be greatly appreciated.  Thank you!

did you enabled Plex Remote in your Plex Server? (settings > remote access) did you check from that setting page if the remote access works? sometimes Plex remotes access works better when you manual enter the port..

- looking at your settings and that guide (and my own config) i see you didn't set "destination port range", change that to 32400
- Plex port 32400 is TCP only.
