Hi All, On www.isatools.org I have found a tool named IPConfig_eng.exe. This tool should allow you to update ISA's policy rules when your external IP addres changes. Since I'm using a cable modem to connect to the internet a tool like this is very interesting for me. Unfortunately there was no documentation along with the executable. So my question is: Does any of you have some experience with this program. What do I need to do to get this program up and running. Do i need tho create a service for it with a program like firedeamon? Thanks for your help. BR, Fokke
