I'm with Zen Internet as well.

I've used the EN5861 and various residential ADSL routers. All have been
fine.

You just need to configure it for pure IP Routing. Be sure to set the
netmask to .248 (that's the one for a /29, right?) on the ADSL router
itself so it does router them over to the 'LAN' interface side.

I recommened the EN5861 if you're lost about what to get. They usually lug
around on ebay.

Good luck!
