In OpenVPN, a daemon is started with a service unit, which connects to a remote side and creates a tunX interface and configures it according to what the other side says. The other side can push basic configuration like IP address and routes that go into the main routing table, but I need a RoutingPolicyRule and addiitonal Routes pushed into the configuration. I tried writing the following tunX.network unit: [Match] Name=tun1 [Network] Description=tun1 tunnel to old torres DHCP=no IPForward=yes IPv6AcceptRA=no [Route] Destination=0::/0 Gateway=2a01:238:4071:3202::1 Table=202 [RoutingPolicyRule] Priority=32100 From=2a01:238:4071:3280::/59 Table=202 [RoutingPolicyRule] Priority=32101 From=2a01:238:4071:32b0::/62 Table=202 but it looks like networkd wants full control over the network interface and flushes the IP addresses from the working interface, leaving it in a non-functional state. Is there any way to (a) tell networkd to just add the configuration from the unit to the already interface without cleaning up first, or (b) to have part of systemd just execute a single .network unit, probably as a sidekick unit that I can use to add configuration to my OpenVPN configuration? Or am I better off by just taking things away from systemd-networkd completely and use an "up" script from the OpenVPN configuration? Hoping for your opinions and a good discussion, cheers, Marc -- ----------------------------------------------------------------------------- Marc Haber | "I don't trust Computers.
