#!/bin/sh
sudo ssh -f -N -w 0:0 my_server
sudo ifconfig tun0 192.168.1.102 pointopoint 192.168.1.101
ssh my_server sudo ifconfig tun0 192.168.1.101 pointopoint 192.168.1.102
ssh my_server sudo arp -n
sudo route add 123.456.789.123 gw 10.0.2.2 eth0
sudo route add default gw 192.168.1.101 tun0
sudo route del default gw 10.0.2.2 eth0


Things you will need to change...
my_server = my server's name
123.456.789.123 = my server's ip
10.0.2.2 = GW in this virtual machine, yours will differ.

It's not pretty but it works for my needs. Oh, and the arp line is there to verify that the arp entry for 192.168.1.102 is still configured on the server side. You may need to add it as explained in the tutorial you're following (same tutorial I was following).
