I have a machine that's a dual homed host running NAT and DNS, connected to 
the outside world with a static IP. It seems I can nslookup 
'www.mydomain.com' from the outside, so I think my DNS responds to lookups 
from the outside.

I am pointing 'WWW' via DNS to a separate machine called web.mydomain.com 
but for some reason from the outside I cannot get to 
http://www.mydomain.com. It is working from the inside however.

My confusion is therefore the following: how can I test that outside DNS 
queries are resolved correctly and why would requests for http://www... not 
get routed to the Web server?

I'm pretty sure nothing relevant (UDP 53 or IP 80) gets dropped by the
firewall btw., I checked /var/log/security.

This is my first attempt at DNS so please be gentle :-) I'm looking for a 
conceptual answer but I can follow up with config files if it helps. I read 
some old posts at 'Ask Mr.DNS' that talked about running 'split DNS'. Is 
that still necessary?


Thanks so much,

Caro
