Hi, After playing around with some configurations with a server, i can explain properly what i need to know (i hope). I have a cisco firewall which is installed right in front of my server, and this firewall redirects all requests for the domain www.npccmauritius.com to the internal IP address 192.168.192.1 (our dns server). On this server we have a web server (http://www.npccmauritius.com) and a mail server npccmauritius.com. I want to create a subdomain on the dns server and delegate it to the internal ip address 192.168.192.2, and then have a website (http://applications .npccmauritius.com) and also a mail server applications.npccmauritius.com running on it. what steps do i need to do on server 1(192.168.192.1) and server 2 (192.168.192.2)? I know that i have to configure to firewall also to route all request for applications.npccmauritius.com to 192.168.192.2, but i have to make sure that it works internally first. How do i do that? Pleeeeeeeeease help me.
