OH, another BigPond sucker, ermmm, I mean victim, errrrrm, I mean customer.

Actually, I should tone it down a bit, BigPond only TRY to be evil these
days. Most of us are fairly comfortable in the knowledge they'll stuff up
most of what they try.

You can grab the bridging file from the Alcatel site, but I'd expect it to
be on the CD somewhere, dunno where though. I was pleasantly surprised
recently when a client got BP ADSL and the installer (outsourced contractor)
had the bridge mode config already loaded, but not active, on their ST530.
