Netopia Router 7100C static route or DMZ

How do you setup a DMZ on a Netopia 7100C? I am using three dsl
connections of which one is a netopia sdsl 7100c, second is actiontec,
third is netopia sdsl 4652.

The Actiontec and 4652 both work fine.

I want to connect the Actiontec dsl and the 7100C dsl to a Xincom 402
dual port router.

The 7100C does not do bridging. Any ideas?
