Yes, I am facing the same issue. Method 1: I am trying to do hiding add settings in the network tab under the Iptux preference setting.

Method 2: Set up the Ufw rules to use for your specified network. Please refer to how to set up the Ufw rules in Ubuntu.

sudo ufw allow in on eth0 from 192.168.0.0/25 to any port 2425

Refer link : Allow Incoming Connections to a Network Interface

Here you want which network to use in Iptux, please added the above command.

It works for me.
