It just hit me that the simplest way to solve your first problem (not being
able to update) would be to look up the server you're wanting to connect to
from a working computer, note down its IP address, and edit /etc/hosts to
include the mapping.

I remember looking at this that Mac OS is simplest to look up information
for using the graphical network information tool in system preferences. If
you're using DHCP, of course, it might be a little trickier, but you sound
like a static kind of person.

Is that from your service provider, or does the router use DHCP to share out

So, what I'm understanding is this:
you have several machines. One is a Mac box that works perfectly. The rest
are FreeBSD boxes that don't work perfectly.
The way they don't work perfectly is that they're not resolving DNS
correctly. Other network services work fine, you can ping out by IP address
etc, just not DNS.
You have either several IP addresses from your ISP, or you have one IP
address at your router/modem, and it is performing NAT/DHCP to handle
transforming your network connection to a shared connection from several
I just want to get a clear idea in my head of the picture of this thing so
that I understand the problem :)
If your router is performing DHCP/NAT, turn one of your FreeBSD boxes onto
DHCP, copy down it's resolv.conf, configure it statically again and set up
all the boxes correctly.
If doing that doesn't resolve things, you may need to know the first step of
your network. Which in your case is probably the private address of the
modem from your ISP. In the case of statically addressing things, I've
always, *always* had to add a line like:
to my /etc/rc.conf
This strikes me as possibly the problem, in fact. If everything else is
switched up, the switches could be allowing internal traffic, but the
computers don't know where the route out to the internet is.
Oh, and incidentally, use "reply all", not "reply". There are a lot of
people on this list who know a lot more about networking than I do, and they
all want to help too.
