Instead of using Clarkconnect that only acts as a cache server and router, why dont you get a SME server software on linux that will both run proxy, cache, email management, dhcp and dns and a host of others. It is what i use and I can assure you that it is the best Linux warez for both local and wide networking.

You can download it for free at their website (I can also give you the free software on CD) but it will cost you money for me to perform a standard configuration for you. You can reach me (Wale) on 08055824984 or 01-8114718.

Note: with it, you can have your own personalised email systems, say wale@nairaland.com, you can run ftp,dhcp, print and so many other possibilities, it even has a user interface on windows. Very beautiful and perfect, you're sure to like it.
