installation issues

unity0110

I am trying to set up an openvpn server that tunnels all traffic through it. I set it up using this script, http://vpsnoc.com/blog/2010/01/how-to-in...instantly/

I am able to connect to the vpn, and I get a dhcp lease from it, but I am not able to ping anything but the vpn, which tells me it's a routing issue, but I can't seem to figure it out. I have posted my configuration @ http://pastebin.com/9LZGMmex

I would appreciate any help you can give! Thanks
