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 :

```auto
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

May 06, 2020 18:46:30.233 [0x7f47d97fa700] DEBUG - Final path: "/usr/lib/plexmediaserver/Resources/Plug-ins-b69929dab/WebClient.bundle/Contents/Resources/index.html"

May 06, 2020 18:46:30.233 [0x7f47d97fa700] DEBUG - Content-Length of /usr/lib/plexmediaserver/Resources/Plug-ins-b69929dab/WebClient.bundle/Contents/Resources/index.html is 10150 (of total: 10150).

May 06, 2020 18:46:30.234 [0x7f4813fff700] DEBUG - Completed: [192.168.0.45:63023] 200 GET /web/index.html (4 live) 0ms 10150 bytes (pipelined: 1)

```

But the device on the other side receive absolutely nothing, and will hang on when the TCP connection close, but without any data :

```auto
~ % 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)

> HEAD / HTTP/1.1

> Host: 192.168.0.51

> User-Agent: curl/7.64.1

> Accept: */*

>

* Recv failure: Connection reset by peer

* Closing connection 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
