I am trying to setup remote access between one computer (server) and a couple of client computers on the internet.
I can make to connections no problem (have been doing this for a few years)
All the computers in questions have dynamic IP addresses (internet) and so use a DNS service.
In my previous experience I have made these connections and just used my static IP provided by my ISP (only allowing that IP to pass through the router and the program itself) and a user name and password to stop any unauthorised access.
Now though as most UK ISPs only use dynamic IPs I am finding it more difficult to keep the server computer as secure as possible.
Though I need to make them a secure as possible with spending little to no money.
Using NIS2K6 installed on the server machine to attempt to only allow certain client computers to connect to the application, but I can not find an option for this. I only see an option to allow or not to allow access to the application.
Using the DLink router on the server side to limited access to certain clients to the port the application is run on is restricted to IPs address or ranges only and there is no place to enter a name for an incoming hostname i.e. happyfeet.no-ip.com
The program itself which I am using will limit what connections are made to it but again like the DLink router only IPs can be entered here and not any form of name.
On this note does the DNS2go/DynDNS/NO-IP etc work in reverse so a client computer running a DNS Service (as it has a dynamic IP) can connect to a server that has the clients DNS name set as an allowed address (hope that makes sense). If not is there a program out there that I client could use that has a dynamic IP to allow them to connect to a server that will only allow connections from a set IP or hostname?
So basically I am trying to set up a computer that can be remotely accessed by a couple of other computers through the internet. All computers will have dynamic IP address but I want to setup the server to only accept a small range of specific connections.
Any help/Suggestions would be appreciated
