Post subject:  Network Address Translation problem? Is there a solution?

Ok, so here's my scenario.

I have a cable connection, with a router (running latest version of m0n0wall) and a 16 port switch. Off that switch hangs my Mythbackend (and several other PCs). One of the PCs is my WinXP machine which is my primary computer for day to day use. I have a domain name pointed at my home IP address. Port 80 is forwarded in the router config to my backend. This allows me to access it work/school/friends house/etc. Everything there is fine.

Problem is when I'm at home, and sitting on a PC inside my network I am unable to reach the mythbox by typing in the URL. I can type in my host name, or type in my internal IP and everything works fine, but it is a hassle as one of my computers is a laptop and is often outside my network. This means I have to setup two sets of bookmarks, one for when i'm in my network, one for when i'm out of my network.

Is there a solution to this? Can something be done so that when i'm at home I can open a browse and click my bookmark and have it load my mythweb page yet have that very same bookmark work from outside my network?

My linksys router has the same problem where it won't forward the ports if it originates from inside the network, yet my ipcop firewall will. The only solution i can think of is to setup an internal dns server with www.yourdomain.com set to its internal ip address.

That was the other solution that occurred to me (after I made my original post for this thread).

What is that setting called in our IPcop settings? Perhaps monowall has something similar that I just need to enable.

On ipcop it just works that way, ive not set any special settings.

Does monowall already have a dns server that you can modify?

I don't think so, but I haven't actually taken a close look... it could very well be there.
