+The custom-made scripts for the init.d file can be used to setup a user-defined |
| 87 |
+routing for the vpnc connection. The examples below show how to setup the |
| 88 |
+routing table so that only connections to 123.234.x.x are routed over the VPN |
| 89 |
+and all other connections use the default gateway. The example uses |
| 90 |
+work-preup.sh to save the current default gateway before starting vpnc (which |
| 91 |
+resets the default gateway using the VPN connection). Once vpnc has been |
| 92 |
+started, work-postup.sh deletes this new default gateway, restores the old |
| 93 |
+default gateway and sets the route for all connections to 123.234.x.x to use |
| 94 |
+the vpnc connection. |
