how to set up bind for a home network

[redhatdude at bellsouth.net]

Hello
I bought a new router that does not resolve to my email server or my  
apache server when I enter my domain name in the browser. My previous  
old Linkys router never gave me this problem. D-Link tech support  
informed me that I needed to set up and run a DNS server inside my  
network of three computers for it to work. Right now every time I try  
to go to my domain the router takes me to its login screen. The  
router is the DSL-504T model.
So, can anyone tell me how to configure my DNS server to resolve to  
my domain name inside my network?
Thanks
