How does NoMachine “advertising on the network” work

[tkarkache]

Hello,

I am trying to restrict NoMachine to only a VPN interface (tun0) which I am able to achieve via UFW/iptables however when I lock down traffic to port 4000 and the UDP port range,  I am no longer able to see the NX server in my NX client when searching the network for devices, I can however succesfully connect if I manually lookup the IP address first.

How does NX announce itself on the network to other clients?

Also is there any specific way to lock traffic to a specifc network interface other than using firewall rules?

Hello,

There is a feature request https://www.nomachine.com/FR09P03687 that could help for your case.

If I am not wrong, when you are mentioning that you dont see NoMachine server in client i am thinking that you need to enable mDNS port as well inside of firewall.

Here is the article about NoMachine used ports: https://www.nomachine.com/AR01L00770.

Thanks @fisherman I missed the mDNS when I was skimming the article the first time, exactly what I was looking for.
