Hi all,

 

i hope there is a easy solution for my problem or i have a bad setting somewhere.

 

I have problems using the VNC remote over the WebUI. The WebUI of Unraid itself is stable, but if i start a docker, a vm or something else over the WebUI, the UI of the service will freeze after around 30-40 seconds. If i restart the UI, the same behavior occurs.

 

This affects also the ssh connection, the connection via smb shares or the terminal application.

 

Does anyone have an idea what is wrong? The problem was not there from the beginning, but i don't know exactly when it first occured.

 

Thanks in advance

Okay, i have found the problem, but not the solution.

 

i have 3 vlans, 10.0.10.xx (Home), 10.0.20.xx (IoT) and 10.0.100.xx (Guest).

The unraid server is together with the router, switch and access points in the 10.0.0.xx

 

If i put my device from where i access the server into the 10.0.0.xx subnet, then everything works fine. But if i put my device in one of my vlans, the remote connection to my services fail again everytime after about 30 seconds.

 

I have a OPNsense firewall and i tried to set a Outbound NAT rule from i.e. the Home VLAN to the server and check the box STATIC PORT. But that does not work either, or i do something wrong.

 

Did anybody encounter a similar problem or can anyone tell me, which firewall settings i have to use? Is the port remapping the problem?

 

Thanks in advance

 

The solution was:

 

OPNSense has a setting under Firewal: Firewall Optimization. This should be set to "conservative". Then everything works fine.
