Hi everyone,
I have a networking issue related to Plex. I understand my setup is complicated, but everything for now seems to point to a Plex related issue.
For the part that interest us :
Plex has the IP 10.0.1.52 in his lan, standard port 32400 for web access. Another network card with IP 10.0.3.10, I can access to the web player through that one no issue. The router on the 10.0.1.0/24 has a nat rule enabled, that allows devices from 192.168.0.0/24 to access port 32400 of 10.0.1.52 via 192.168.0.51 (address of the router on the other network)
But no device in 192.168.0.0/24 subnet are able to access the Plex web app.
They are able to connect to the Plex server, establish a TCP connexion (confirmed with nc -l 32400 on the server side, and connection with 192.168.0.51:32400 on the other side)
The Plex server sees the connection since in the log I have :
May 06, 2020 18:46:30.233 [0x7f47d97fa700] DEBUG - Request: [192.168.0.45:63023 (Allowed Network (WAN))] GET /web/index.html (4 live) Signed-in

But the device on the other side receive absolutely nothing, and will hang on when the TCP connection close, but without any data :
~ % curl -vI 192.168.0.51
* Trying 192.168.0.51...
* TCP_NODELAY set
* Connected to 192.168.0.51 (192.168.0.51) port 80 (#0)

curl: (56) Recv failure: Connection reset by peer
Any idea where to look for ?
Thanks,
Simon
Server Version#: 1.19.2.2737-b69929dab
Player Version#: 4.22.3
Edit : the redirection is so that it’s 192.168.0.51:80 -> 10.0.1.52:32400, and tested nc with 192.168.0.51:80
