[lug] Little Network problem

[David Howland]

Most likely the DSL modem is providing NAT already. The 4 addresses
are most likely a network address, a broadcast address, your modem's
external IP and the IP of the gateway you will use (or your modem's
next hop).

A .2 address is fairly unlikely on the public internet if you're
already getting subnetted to that small of a range. I agree that
knowing the full address would be very helpful and give a lot of
information about what is going on.

If you're getting a 192.168.X.X address you might try setting a static
IP of the full .2 address incremented by one.
Set your modem (probably .1) as the gateway then try to hit its web interface.
