[nm-libreswan] set static routes without knowing the assign ip address



Hi,

is it possible to add static routes when you don't know the ip that will gonna be assign by vpn server?

The idea is to use  connection only to connect to the remote networks, all the default traffic should not be sent to the vpn.


In configuration IPV4, I set routes:

Routes Automatic: Off

address: 192.168.8.0

netmask: 255.255.255.0

gateway: 0.0.0.0

x - Use this connection only for resources on its network.


When connecting, the route is added but no traffic! This configuration works with nm-vpnc

ip r shows:

192.168.8.0/24 dev wlp3s0f0  proto static  scope link  metric 50


Since i know the ip address of the vpn, i know set the routes:

Routes Automatic: Off

address: 192.168.8.0

netmask: 255.255.255.0

gateway: 192.168.20.3

x - Use this connection only for resources on its network.


This works, i see the route and the traffic to remote network is ok.

ip r shows:

192.168.8.0/24 via 192.168.20.3 dev wlp3s0f0  proto static  metric 50


Could be a nice feature to detect the assign ip address to the vpn and replace the 0.0.0.0 when configuring the route.


BTW, tested with git version, last commit b2a4514a78d39e2f4c9760d655e9a762be2c5f96.


Thanks.

António
