I hope this is the correct newsgroup - here goes.
I have a webserver, two nics, one internal ip the other a 10.0.0.2 ip. This
always was reachable from my office via the url and/or link from our home
page until today when a new firewall was installed. The firewall config had
to change the web's public ip which caused it not to come up until our isp
changed to point to the new ip, now I can reach the website from outside our
LAN, but cannot reach it from inside our lan by its url - can reach it by
typing in the 10.0.0.2 address however.

What caused this change? and how can we change it back so we can reach the
site from the url? We did have a previous firewall which did not give us
this problem.
 
It depends on your DNS. Do you have an internal DNS or are you using ISP DNS?
