Help with fireawall rules - Plex Remote Access

Having an issue with Plex Remote Access that I have narrowed down to a "block all traffic from internet rule".

These are the rules I have going on that apply:

- All Devices - Block Traffic from Internet (default rule)

- LAN X - Block Traffic from & to All Local Networks, Block Traffic from Internet

When I port forward through "Network Manager -> NAT Settings -> Port Forwarding" I set up this rule: Protocol TCP, External Port 32400, Internal Port Device [Plex Server], Internal Port [Port 32400]. Allow on Firewall - Yes (this creates a firewall rule that allows Traffic from Internet on Plex Server, TCP Port 32400.

But when I try to remote access, the connection is blocked. And I can see it blocked in the firewalla app, "Blocked [ip address] from accessing device [Plex Server]". On the [Plex Server] device information, it shows Port TCP 32400, and in the source device information, it shows [ip address] and port TCP 1779.

I'm guessing I have something messed up here, but if I disable the LAN X "Block Traffic from Internet" rule then remote access works just fine. I thought the allow rule created by the port forward would allow this connection, why is it not?

  You do not need a block traffic form internet on the LAN segment.  You should already have a rule blocking traffic from internet to all internal devices, that's should be enough.

  This solved my issue. I guess I had a double rule on all internal devices and then also on the LAN X to block all traffic from the internet. So port forward would send it through the first rule, to be blocked by the second. No way to write another rule to get through because it would say the policy already exists", so I did disabled the "LAN X - Block Traffic from Internet". Solved my issue thanks!
