Thanks Tim,

I'll definately try that out when I've sorted out my routing issue.

Problem I have is that the WAN interface has an IP assigned from the 
same /28 range as I want to give to computers on my network, I don't 
mind losing an interface, but I need to use DHCP to assign IP's from my 
/28 range to computers on my network then throttle their upstream and 
downstream connection to the internet.

I don'w know what subnet to assign to each interface so that out of my 
/28 range the WAN has one IP and the rest are available to my machines 
on another interface without NAT or bridging, you may have quessed I'm 
not too up on my IP addressing and stuff ;-)

Cheers, James....
