Re: can't configure networking for static IP address
Sorry… I'm a couple of days behind on the list, but it doesn't look
like this was ever solved for the OP.

ports on the router. One of these is a Windows box, and the other
is my
Debian system.

Based on the description in your most recent message, your Debian
system is *not* connecting to the Internet when you use DHCP.
Technically, it is connecting to the TrueMobile router. Everything in
your house is on a private network, including the router. What makes
the router special is that it is also on the Internet and it can pass
certain traffic from one network to the other. Your publicly
addressable IP, static or not, belongs to the router (or whatever
happens to be connected to the cable modem).
If you want the Debian system to use that IP, it's going to have to be
plugged directly into the cable modem. This introduces some security
concerns that have already been discussed, so only you can decide if
that's really what you want.
Since you're learning your way around, I think you should leave your
Debian system on the private network for now. If there are particular
services you'd like to access from the outside world, you can probably
forward the appropriate ports to it using the router's config. (Again,
this introduces additional risk, but not as much as putting the
machine on the Internet directly.)
If you just want to learn about configuring Debian with a static IP,
you should be able to do that. Just use an available IP on the private
network (192.168.2.X). Preferably, choose an address that's outside
the range the router uses for DHCP assignments.
