[Openswan Users] Strongswan not routing XP client

[Craig Chandler]

Hi all, i'm trying to configure a VPN tunnel through a Strongswan 
gateway like this:-


            o|Gateway|o=================o|XP Client
192.168.0.50         192.168.34.1      192.168.34.137
          ||
          ||
          ||
          ||
          o
          -
      internal lan
      192.168.0.1

currently i can ping the 192.168.0.50 from the XP client but not 
192.168.0.1 and i cant work out why...?

kernel version 2.6.10
Strongswan version 2.3.0

ipsec.conf file

config setup
           interfaces="ipsec0=eth1"
