systemd-networkd-vpnc

This is a glue between OpenConnect and systemd-networkd. Works by replacing vpnc-script.

Installation:

cargo install systemd-networkd-vpnc --root /usr/local/
cp units/cisco-vpn.netdev units/cisco-vpn.network /etc/systemd/network
networkctl reload

After it's installed, add --script=/usr/local/bin/systemd-networkd-vpnc option to your openconnect command. For instance:

openconnect --interface=cisco-vpn --script=/usr/local/bin/systemd-networkd-vpnc \
    --csd-wrapper=/usr/local/bin/csd-wrapper.sh --csd-user=myname --protocol=anyconnect \
    --user=corporate.user@company.com vpn.company.com

The script generates /etc/systemd/network/cisco-vpn.network.d/routes.conf drop-in config file and reloads config, so systemd-networkd handles VPN network configuration.

After VPN connection, if everything went well, you will see the following status:

$ networkctl
IDX LINK      TYPE     OPERATIONAL SETUP      
  1 lo        loopback carrier     unmanaged

  4 wlan0     wlan     routable    configured 
  9 cisco-vpn none     routable    configured
