I believe I'm on a 21CN line from Eclipse so that sounds promising.

Eclipse sent me a Zyxel AMG1202-T10A which claims to do RFC1483 bridge
mode so perhaps I'll do some experiments.

I asked Eclipse what they recommend and they suggested using two IP
addresses and disabling NAT on the router. This sounded like it would
work too and it apparently wouldn't cost me any more but it would mean
changing IP addresses and more reconfiguration so I would prefer to
just stick with one.

Thanks to both of you for your swift replies.
