Ok here is the situation: I have a piece of software called Time Guardian that connects to biometric punch clocks at my company's warehouse. The punch clocks get a LAN IP through DHCP, which is then entered into Time Guardian so that it can connect. Over LAN this works perfectly. Now, I need to connect Time Guardian to a terminal (punch clock) at a remote location. To make this work I had to place the clock in the DMZ of the remote network, and point Time Guardian to the public IP of that network. This also works fine, but the remote office does not have Static IP, and we don't want to pay to get it. So, when the public IP of the remote office changes I have to update the IP that is stored in Time Guardian for that terminal. I had the idea to use a dynamic DNS service to solve this problem, but the Time Guardian software will only accept an IP address not a URL. My question is, does anybody know a way so that I can put an arbitrary unused IP address into Time Guardian that will forward to a DynDNS.org URL. Am I crazy or can this be jury-rigged? I am running Windows 7 Ultimate. Thanks in advance.

No you can not do as you ask, you have it backwards, DNS resolves DOMAIN names to IP not the other way around. You should look at VPN end points (cheap as 50 ~ 75 bucks each)
