Nixos should run these automatically but does not:

ip route add 192.168.12.0/24 dev wlp6s0 table 1
ip route add 192.168.12.0/24 dev wlp6s0 table 2

What are the symptoms? From what I see in the systemd scripts, it does apply, but it does not appear in the routes table. Is that it?

What are the symptoms?

E.g. Mattermost inaccessible while connected to the wifi (since the wifi client may choose the HKBN IP address which requires policy-based routing on the server).

After renumbering

ip route add 192.168.0.0/24 dev wlp6s0 table 1
ip route add 192.168.0.0/24 dev wlp6s0 table 2

After renumbering ``` ip route add 192.168.0.0/24 dev wlp6s0 table 1 ip route add 192.168.0.0/24 dev wlp6s0 table 2 ```
