the host thats running the VM, is it connected to a LAN behind a 
firewall/router, or directly to the internet? if directly, is there a 
dedicated internet IP address that the VM can use? if yes, then you 
want a bridged network where the VM uses that dedicated internet IP 
seperate from the host's IP.

Right, its connected to a router. The host acts as an internal router
for machines and devices on the LAN.

if its on a LAN with private addressing, you want to use a dedicated LAN

IP address, seperate from the host's LAN IP, but since its behinda NAT 
router, I really don't know how you'd expect it to use DDNS as that will

only see the router's internet IP address.

This is what I was seeing. Either it lands on the DSL router's login
page or the host's website.

I guess this is why I'm confused. I thought a VM could be setup as its
own domain with all available services.
