Hi, I ecountered an issue since I migrate Plex server from my NAS to my MacPro (the NAS wasn't powerfull enough for AppleTV stream).
Here is how it's configured :
- Mac Pro (El Capitan up-to-date) with IP adresse fixed 192.168.89.10 - OS X Firewall disable
- Synology with IP adresse fixed 192.168.89.2
Movies are stored on the NAS with share mount on the MacPro.
My router (Livebox Play - Sagemcom Livebox 3) is configured this way :
- DMZ to my NAS (for other services)
- NAT 32400 (TCP) to the MacPro.
- UPnP is enable
I check other NAT ports to MacPro (like 22 or 5900) : it's working fine (check with telnet and canyouseeme.org).
But Plex Server still unavailable from outside.
Firewall disable on the router doesn't change anything.
When trying to telnet from inside (telnet 192.168.89.10 32400), everything is ok.
I also try to put DMZ on the MacPro IP, without any success on the 32400 port.
If I put Plex Server on the NAS, it works fine wherever on DMZ or NAT routing.
So, I understand that the problem is on my MacPro, without understanding why.
I won't have any special applications on the MacPro (like Iceblock, or Little Snitch).
lsof -i in terminal confirm that it's listen on right port :
Plex\x20M 22510 user 62u IPv4 0x881dfef5ba74a37 0t0 TCP *:32400 (LISTEN)
Someone could help me on this issue ?
