Grant it I dont know much about Nat...but what I do know
(its a standard proxy program that tunnels local addresses inside global
address) is that its not terribly suffisticated (neither is my spelling
:) ) ...no
rules, filtering, portblocking, logging...I should have realized though that
you where going to run a firewall along with it on the same box
(although you did mention only NAT)...but in either case I would still opt
with an external modem for two reasons...first, you have only to worry about
buying an inexpensive 10baseT card if for some reason BSD doesn't like the
hardware...and secondly...you can take advantage of your ISP's DynIP
policies
(if the need ever arrised)....and ahh by the way...would you
happen to know why my pointer looks like a big white block in X?...
:-)...yes I'm sure you have arived at the conclusion (by looking at the
above
ramblings) that I'm not very safisticated when it comes to freebsd either.
thanks
Adam

absalutly don't buy that piece of crap and expect it to work with BSD...My
friend had one that he wanted to use with W2k...and of course they didn't
even have drivers for that (so I doubt even linux would be
supported)...Also...check and see if your DSL provider offers multiple
Dynamic IPS...usually the big telco ISP's do, and if so try to get an
external modem, and a hub (you said you where going to use NAT, so I take it
that your not to concerned about security)...I don't know what area your in,
but where I'm from (Southern California) they offer all CPE for free...If I
was you I would try to find the same deal...try to haggle a little...see if
anything comes of it.

only problem is, I'm not getting a dsl modem from my telco, so I have to
purchase one elsewhere. The best one I can find is an internal 3com PCI
adsl ATU. Does anyone know if this is supported under Freebsd 4.0-Stable?
If not, will it be if I upgrade to current?
