[clue-tech] Qwest Choice Internet Basic (DSL) Gotcha - bridge mode not supported?

[Glen Newell]

First of all, for those who are wondering... Yes, its true, The
actiontecs are CRAP. They seem to require being reset from time to
time for no apparrant reason, and about 1 in 5 ( in my experience)
fail to operate as designed and Qwest will deny it all day long. FWIW
, it's worth the struggle to find someone who knows that the Ciscos
are still available (even refurbs) and can get you one, or get an isp
that has them or something similar.

- echoing whats been said: check that the gateway and subnet addresses
are correct...also, check that the built-in filters are setup to allow
connections (the new standard is usually to not...)

 This bridge complexity escaped me previously.  I made an assumption that the

- Bridging is not necessarily what you need, but regardless, these
modems will do ( are supposed to do)  what you describe, though not
very well. Your best bet is to get a small switch on the inside, or if
you can swing it, another router that can do dhcp and nat
independently ( especially if you want the machine in your lan to talk
to one another...). As an out-of- the box solution, the dlink routers
are pretty good, and easy to setup.

Better to use static private IPs if it comes to that...static
world-accessible ips is unecessary unless you have internet-facing
services.
