[TriLUG] Home DNS

[fumiko]

I'm interested in discontinuing my web hosting contract, which provides 
a website and email.  My domain name is registered through GoDaddy and 
I've made the MX record change to point my email address to Gmail.  That 
worked fine.  I'd also like to point my domain name to my home machine 
on TWC Residential.  I've been using DynDNS on my DD-WRT router to 
update a domain name for my home network, but I'd really like the domain 
name I purchased to point there.

Any ideas about how I might do this?  I suppose I could point my MX 
record to Gmail and forward my domain name to the DynDNS domain name.  
Is there a better way?

GoDaddy's DNS control panel is kind of confusing to me, probably because 
I don't have a lot of experience with DNS.

Thanks!
