push route net_gateway does not work
push "route 22.214.171.124 255.255.0.0 net_gateway"
is ignored. The pushed route is mentioned in the NetworkManager log:
NetworkManager: <info> […] Data: Static Route: 126.96.36.199/16 Next Hop: 188.8.131.52
(The gateway is even correct.) However, no route is actually added. Interestingly enough, a
push "route 184.108.40.206 255.255.0.0 vpn_gateway"
is added to the routes. Wild guess: Possibly, the device is wrong, because a manual
# route add -net 220.127.116.11/16 gw 18.104.22.168 dev tun0 SIOCADDRT: Network is unreachable
fails obviously. Instead of “tun0”, it must be the normal net device for which the gateway is valid. But again, this is only a guess.
