I’ve setup my third ipfire application these days, mostly used in combination with OpenVPN - which is great. But quite some time I’ve struggled with the topology settings.
The default behaviour of the clients is to use net30, however according to OpenVPN the recommended setting is to use topology subnet (Topology - OpenVPN).
Since there is no option in the gui, you have to add it manually in the config file. And if a person stops the server, changes configurations in the gui und restarts the server, the settings are lost.
Furthermore, if you change the static ip address of a client via the gui, the ccd-file is also altered and the subnet-masked is changed (always to net30).
It would be nice if we had an option in the gui to change the topology.
