Noob sudomain/firewall question

[countdrak]

I am running a Windows 2003 server with IIS. I have two sub domains

http://x.mydomain.com

and

http://y.mydomain.com

I want x.mydomain.com to be visible only to computers on my network, so I want them to be visible only internally like and intranet. I want every other subdomain and

http://www.mydomain.com

to be visible to everyone.

How would I achive this. Any help would be great. I am trying to setup my own server, but I am having issues.

Thanks.

My suggestion. On the IIS server install two NIC cards. One NIC for internal and the other for external. Assign the NICs (IPADDRESS) in the properties of each web-site. Disclaimer - since you are doing external web-site make sure the IIS server is in a DMZ and proper ACL configuration on the firewall prevents you internal network from getting hacked....
