I think ACS is not supported in NAT environment because it dynamically changes the ports being used by the ACS admin page, Also i think i read somewhere that the ACS admin port can be made static.

However it is not recommended to publish ACS onto the internet.

But this cannot logically be true for UCP, because, one of the major features of ACS authenticating remote access VPN's. So remote access VPN users are basically outside the LAN environment environment and also the remote access users access resourses other than that existing in the LAN where i have the UCP server.

So i require then to change the password without accessing the Local LAN where the server exists, and the best possible way is through the internet directly.

And i have seen a similar kind of problems with many other pages in the internet when i was browsing, like i can access all components on a page and when i click on one particular component, it looks for a private address and the connection times out, there must be a solution.

lets see if someone else can answer.

I need to rate myself, actually the UCP software must have asked me for the ip address of the sevrer when i was installing it, i must have entered the private Ip and the software hardcoded the private Ip in all the HTml pages thats y it was causing problems when accessing from the internet, i finally got it working.

Thanks a lot everyone.

UCP is accessible well from the internet now.
