Setup incoming VPN over cable-modem connection

By joelicketto ·
I am looking for information that will allow me to connect to my home office network using Remote Desktop. I have an Active Directory domain network setup for file and print services and connect through a router/firewall and cable-modem.
My problem appears to be that since I am using Charter Communications cable access (DHCP connection that changes approximately once every few weeks), that I can't locate my domain through their network.
I also can't find any information that will allow me to make the desired connection. My regular office is a major corporation and we have the ability and software to VPN into the corporate network to do remote support sessions. However, I'd like to be able to got the other direction or to access my home network from the road when I travel.
Can anyone help point me in the correct direction to get what I am attempting to accomplish?

Ask your ISP

If you don't mind spending the extra cash, most ISP's will offer a business class connection for your home, that will give you a static IP address.

I have found that using a router somethimes "holds" onto an IP address for a much longer time (eventhough it might give a "IP Renew Date"). Otherwise there isn't much you can do without static IP. I have DHCP with a router and it hasn't changed in over two years. I agree with the previous post..Static IP is your best bet. Good luck.

Dynamic DNS

I also have a dynamic IP at home but am able to VPN into a Windows 2000 server using dynamic dns. is one of the sites that offers free dns resolution for people with dynamic IPs. All you do is install a client program that runs in your system tray and periodically updates their zone file with your IP address.

This way, I can type in '', and it always resolves to the current IP of my home server.

You may still have to open up ports on your firewall to connect. I use PPTP as my VPN protocol so I port-forward TCP 1723 on my firewall.
