Redirecting Public Domain Name to Local IP When At Home

Good Afternoon -

I have an extensive home network which amongst many things includes hosting of a few different resources which I access locally and remotely.  When connected to the local WiFi, I access these resources via hostname or IP address.  When remote, I access them through a public domain name which I have pointed to my home network.  Below is what I'm talking about...

To Connect to Media Server / File Sync
- When Home (Connected to Local WiFi) I use 10.10.0.200:4444
- When Away from Home, I use mynetwork.net:4444 which obviously has a different, public IP when not connected at home.  (Ports are forwarded in router)

The Issue
The issue is that some of my services only allow you to enter a single host address so I must change it between the two above (for a few different apps) when at different locations.  This also includes bookmarks for services I host on one of my home services.

What I've Come Up With To Resolve So Far:
- Edit Hosts File on Each Device
I could edit each device's host file (if possible) by adding mydomain.net 10.10.0.200 which would work fine when home, but when remote it wouldn't.

- Create a DNS Entry on Router (Current DNS Server)
I don't have them on a domain and my home DNS server is a WNDR4500 Router which I cannot find a way to edit DNS.  

- Flash Router with Firmware Supporting DNS Editting
I have used DDWRT before and playing around now with OpenWRT on a different router.  I don't know if it supports DNS editing, but wouldn't see why it wouldn't.

- Use a Web-Based DNS Solution
I've tried, but don't currently use OpenDNS as a couple of sites didn't work well with it.  I don't know if adding entries is possible with it, though.  If so, is it the best to use or is there a better, more technical one?

- Create new DNS Server (and edit DHCP to use it for all devices)
I would think this would assume this may be my only hope.  If so, what's the best platform to use?  My primary "server" (Win7x64) which hosts most of the services, a dedicated box, or other?

Any Suggestions?  If you need any additional details or have questions, please let me know.

Thanks Guys!

I've done the hosts file change before.
I have 2 copies of the hosts file.
I create a batch file that will copy external host file to hosts(to use when I am away)
I create a batch file that will copy internal host file to hosts (to use when in)

create shortcuts and its one step to switch from internal or external hosts file

You  can use your primary Win 7 computer as DNS server.

It says it is free and simple but I never used third party DNS server other than MS before.

Thanks.

Thanks Guys -

I actually found a different solution which worked perfectly.  I installed DualDNS on my "server."  All I had to do was:
1. Install the binary I downloaded
2. Open the text based config file in the install folder and configure as desired
3. Start the service it installed (DualDNS)
4. Point my DNS to it

Unfortunatly, I found out that even though I have a top of the line router (WNDR4500), there seemed to be no way to edit what you wanted the DNS to be for the DHCP scope.  Luckily, DualDNS is also a DHCP server.  I disabled DHCP on the router, configured DualDNS DHCP via the same config file, then started it's DHCP server.

Worked like a champ.  Thanks!
