To test whether DNS is an issue, add the hosts names and IP addresses to
your hosts file. Bring up a fresh browser. 

Another variation on theme is to use nslookup or dig to see how those
virtual domains are resolving from within your network.

Subject: DNS I think


This is prolly a stupid question for you brainiacs, but here goes.

I have a Redahat machine connected to my cable modem acting as a firewall
and router using iptables. In my network behind it I have a WIN2000 Server
running IIS5.0 which has 3 vitual websites running on it. I have 3 domain
names which all have had the IP address of my static IP address of my cable
modem (and the Linux box port forwards to the WIN2000 Server box) config'd
with internic. Here's the question,,,,when friends use a browser and hit one
of the domains, www.mydominname.com, they get the correct page, however, if
I try to hit the same www.mydomainname.com from one of my boxes inside the
network, I get "The Page Cannot Be Displayed" with 

Cannot find server or DNS Error
Internet Explorer 

at the bottom.  I believe by setting up a DNS on the Linux box(which I don't
currently have) I may be able to resolve this problem, or so that is my
suspicion. But I'm wonder why if when my request packet goes out and hits
the Name resolution address configured with the Linux box, why it can go out
of my internal address for eth1 and hit the resolved addres, which is eth0,
which should get port forwarded to the internal address and the response
from the IIS go back.

I may not be making any sense at this point, but I was wondering if my
suspicion is correct, and if anyone could tell me or point me to an
explanation?
Or, could this be an IIS issue?

Total nOOb question to be sure
Steve
