Hi, For this to work there are 2 things you need to configure in your gluetun container (assuming all your apps using gluetun have their network type set to container and container set to gluetun) First set the variable FIREWALL_OUTBOUND_SUBNETS to the subnet corresponding to your LAN (example: 192.168.1.0/24 for a local network in the range 192.168.1.x with the subnet 255.255.255.0) Secondly you need to map the corresponding port of your app using gluetun on the gluetun container itself. So, on the container edit page, you simply add a new port. As an example for rdtclient , you add a new port, name it how you want and set the host port and container port to 6500. Hope this helps.
