HELP VPN: Setting Dynamic IP for XP IPsec Tunnel

[lasergecko]

In step 7 of the instructions you have to provide a WAN ip address of your router, is there a way to give it a dynamic DNS domain so that you don't have to set the IP every time it changes?

Insturctions:
Connecting Windows 2000/XP to a Linksys VPN Router Support Page

Yes and No.

ddns service normally require a small software installed on a computer so that it can update the ddns server when your IP changes.

The only way you can do this is to check the WAN ip address on your router dailey and update them on the ddns server everytime you see it changes. With comcast my IP address normally changes no earlier than 3 month. At least this way, you dont have to remember the ip address only the domain name.

Basically, my question is how do you setup the ipsec tunnel setting so it automatically gets the current WAN IP address? Is there anyway to do this?
