I have all set and downloaded

no-ip.com client on my windows 2003 but when I tried to login, its failed. I’m running ISA 2006 on the same machine and want to allow NO-IP to connect from home to my office server because I have dynamic IP at my office.

which ports I have to set allow in ISA 2006 to make sure that I ‘ll have no issue with no-ip client running at my office?

TIA
Cheers
