GL-E750 LAN: share devices with custom ports opened

Technical Support for Routers

Hello ! I am owner of GL-E750.
Is it possible to share LAN between devices with custom ports opened ?

For example, i have two connected devices:

192.168.8.212 - wire connection (smart TV)
192.168.8.157 - WiFi connection (PC)

So i installed HTTP server on PC 192.168.8.157 on port 8080.
Opens fine in browser on the same machine http://192.168.8.157:8080.
Trying to open same address on smart TV 192.168.8.212 from browser - it says can’t establish connection.

What can i do to make every device connected saw 192.168.8.157:8080 ?

Thank you)

Have you enabled the discovery option (assuming u are on windows)?

Here’s a youtube video on how to do this on windows 10

From the text I can imagine three possible issues:

  1. The ‘server’ (192.168.8.157) has a firewall that is blocking external communication
    → To test it could be useful to check with a ‘smarter’ device than a TV, maybe a mobile phone? Better a laptop.
  2. The the SmartTV tries to open a https:// connection, but the service don#t know how to handle https:// …
    → Instead of 192.168.8.157:8080 you need to type http://192.168.8.157:8080
  3. The Service at :8080 is using some language the SmartTV doesn’t understand.
    → When I open 192.168.8.1 with one of my tablets (cheap Android 5.1.1) the site is blank. The behavior of “I can’t handle this” is sometimes misleading.

I don’t think it is a routing issue in the GL-E750. It is possible to separate the clients, but in my opinion a little to complicated, sou you should do it on purpose.
