[vpn-help] Routes on Linux

Hello All,
It appears that routes are added incorrectly (by hostname?) on Linux
using ShrewSoft client 2.2.1. Obviously, what is specified as the
gateway for the 192.168.95.0 (remote network across VPN) network via the
tap0 interface is not a valid route or resolvable by DNS. Below are the
routing tables (one on linux, one on windows) using the same VPN client
policy and configuration. Both negotiate successfully but only the
windows connection properly routes traffic. Has anyone else seen this
behavior?
I am using Fedora 19 3.11.6-200.fc19.i686.PAE
