Any help on this one would be gratefully received.
 
I have set up a VPN between two computers running Windows XP, one on Broadband which has a static IP address (Class as Server), the second has dial up account which is allocated an dynamic IP address.
 
I have setup the Windows VPN Which will work fine when Norton Firewall 2003 is not running. When Nortin is running the VPN will not work which I would expect. I then add the IP address of the dial up computer into the "Trusted Zone" list and the re-establish the connection which works.
 
The problem I have is that the IP address of the second machine is dynamic and changes every connection (ISP). I then registed with NO-IP.com and have removed the ip address from the "trusted zone" component of home networking and replaced it with the no-ip dns entry, unfortunately the connection will not work. when I ping the no-ip dns name is returns a matching ip address issued by my ISP.
 
My only other way is to "allow all internet communications" which I do not want to do.
 
Any ideas ???
Many thanks in advance
