Firewall Behavior / Default Settings 7 Months, 2 Weeks ago  
Hello,

Still learning about ClearOS and have came across an issue that I believe relates to the firewall. I'm trying to have a system on the lan that is running Plex be exposed to the Internet (TCP Port 32400) but am not having much luck.

1) By default, does ClearOS have any restrictions on outbound traffic generated from the LAN? In other words, can all LAN traffic reach the internet by default?

2) I've attempted to open port 32400 by going to Network -> Incoming Firewall -> Allowed Incoming Connections and adding the Plex Media Server service....still no change though.

Thanks

1. Nope...no restrictions by default on egress traffic

2. You said "Plex on my LAN"...so it sounds like you have a ClearOS as your gateway, and a Plex server (on another physical machine) on your LAN.

If that's the case, you don't want an incoming firewall rule (which opens the port to the ClearOS/gateway). You want to forward port 32400 back to the server IP where the Plex media server is running.

Install the port forwarding app and create the forwards (and delete the incoming fw rule you made). FWIW, I forward 32400 on both TCP and UDP...never bothered to find out if one is redundant.

Another thing I had to do for My Plex server to access MyPlex is use the Plex interface, go to settings --> Plex Media Server --> MyPlex and click on "Show Advanced Settings". I had to check the "Manually specify port" checkbox and click "Connect to Server" for mine to work. YMMV

1 - It is up to you. The default is to allow all outbound traffic and specify blocks, but it can be reversed.

2 - The incoming firewall is for traffic destined for ClearOS and not the LAN behind it. Port forwarding allows you to access a LAN device from the internet.

3 - Have you considered running Plex in ClearOS? There is even a (free) front end app for it.

Thanks everyone - that did the trick.

Also, I did consider running Plex on my ClearOS box but with my HD movies and such I don't believe the hardware can handle the transcoding. My dedicated Plex box is an i5 box with 8 gig ram, etc. My Clear OS box is a Pentium 4 1.4Ghz with 2 gig ram

If you are transcoding then your P4 is low powered. Being me, I'd try to turn your i5 box into a Plex server and ClearOS gateway and save on a few bits of electricity (I'd also install cpuspeed to allow the cpu speed to throttle back when not needed).

That is a great idea, I would totally do it but all my content is stored on a NAS device...I've never been able to get Clear OS to connect to it (in windows you'd just map a drive letter to the device) any ideas how to do it in Clear OS?

Have you seen this for mapping remote shares? You may want to map them straight into the Plex file structure or map them elsewhere into ClearOS then symlink them into the Plex file structure. Note I've never tried this but don't see why it would not work.
