Hey Guys and Girls

With the onset of the new File Sharing laws i have decided it be best to stop using p2p and have decided that Hulu/Netflix etc will be the way to do tings now but i have an issue and would like some assistance/advice from the wider Geekzone family

my lan layout is pretty basic as below

ADSL modem/Router (Netgear DGN2000) -> NIC1 in Server -> Switch (on second Nic) then all devices e.g Laptops via wifi Ipods/Android tablet, PCs and a Networked media Tank in the lounge.

What i would like to do is set the server that has the 2 nics i setup the vpn and as such all devices would send traffic via the vpn.

this only seems to work for the server and not the devices on the lan. i figured it is the routing table but not sure where to start. i am running a squid proxy on the server and if i set the browsers on the pcs to use it the HTTP traffic goes via the VPN fine but i want ALL traffic to go via it. 

I know i could get a router that would solve all this but at the time of writing i am being a tight arse as i should be able to get it going in the current config

All help is warmly welcome the easier i can make Hulu and the likes for the rest of the family from their devices the better

Look forward to some suggestions
