Confusion about Running a DNS and a Domain with Dynamic IP

[AsymptoticCoder]

I have a domain name, say mydomain.com, and would like to use it with my home network.

Since I have a Dynamic IP, I am using DynDNS' Custom DNS package. But this only forwards the top-level domain to my dynamic IP. I cannot specify anything further.

I would like to be able to access the computers on my network (which are behind a router/firewall) using an internal DNS name that I must setup.

For example, if I type in www.mydomain.com, the request will be forwarded to port 80 of my Linux server (Apache). If I type in xyz.mydomain.com, the request will be forwarded to the server xyz in my LAN.

I am confused about how I can do this. Any suggestions or advice? How can I set this up?

No wonder I haven't gotten a response...I posted in the completely wrong forum!
