The reason I don’t locate plex server between External Firewall and Internal is because file access and other reasons.

Would it be possible to get Plex device within External Firewall to communicate with Plex Server even though Firewall is in between them.

Thank you so much for your answer

Yes, it can be made to work.

Hi Trudge,

Could you please explain me a bit more how would I make it work?

Since all the Devices will you Plex App to connect to Plex Media Server.
Should I create Port forwarding in Internal Firewall to Plex Server?

I can’t be 100% on this without seeing a lot more of your config.

Assuming the internet connects into your external firewall, all you NEED to do is create a double port forward of TCP 32400 through both firewalls to the server IP so it can be connected. This will cause all your wifi devices to transverse both firewalls though in order to get to your server. It also assumes you are allowing all traffic through both firewalls to head outbound unchallenged.

you can enhance that by permitting your external subnet to connect through your internal firewall to your server IP on port TCP 32400 and putting a static route on the inside interface of your external firewalls directing traffic to 192.168.0.120 via 192.168.1.111. Not knowing your existing config, this could break much more than it fixes.

Hi Trudge,

Thank you so much. It was a very clear explanation.
Currentyl I am using Pfsense firewall. I set Port Forward on Internal Firewall only.

My Internal Firewall WAN IP is 192.168.1.132 LAN IP is 192.168.0.254
Plex Server is 192.168.0.61

So far I set any device looking for port 32400 will direct to 192.168.1.132 and Redirect to 192.168.0.61
But I received an Error message from Plex when I try to add server

''A connection to a Server couldn’t be established using the details you provided
Error code: 401 ‘’

Do you think I should set port forward in External as well since the Server is behide Internal Firewall?

you need the port forward on both firewalls.

External firewall = Port XXXXX forward to WAN IP on internal firewall Port XXXXX
Internal firewall = Port XXXXX forward to Static IP of Plex server Port 32400
In plex server config enable “Manually specified port” with XXXXX as the value.
