I have been running NetBSD 1.4.1 on a Sparc IPX for some time now as a firewall
for my home network. Recently my DSL was reprovisioned and as a result, my
fixed IP address changed. Following this event, I reconfigured my system and
it seems to work for the most part, but now there are a few URL (IP addresses)
which I have trouble reaching. My IP address changed from 4.3.176.50 
(255.255.255.252)
to 66.14.78.22 (255.255.255.252). One of the IP addresses which I can no 
longer reach
is 66.236.61.165 (pelicanparts.com), the other is 216.32.120.133 (ebay.com).

If I just attach a windblows box to the DSL line, I can reach these sites 
just fine.

Does anyone have any suggestions as to which item I might have misconfigured,
or how I figure out what is the problem component?

P.S. I know that I should upgrade the OS to a later rev, but that isn't as 
high on my
list as getting this problem solved.
