how to make kaspersky as router

hello .. i have internet access by 3G modem  and its attached to a computer (let's call it the main computer ) and shared "iCS" to a network .. of two pcs .. " the total pcs is 3"  and each pc i have kaspersky 7 internet security
and i need to access this network from the out side i meant over internet
so i installed dynamic dns client from the dydns site on one of the computers and and this program can give me a hostname over internet and linking to my ip address
so when i try to open remote desktop from out side this network ( and of course i disabled the windows xp firewall and the stealth mode on kaspersky) it allows me to open the main computer
so what i want is to find somewhere in kaspersky internet securty 7  .. or ( if there's not such a solution in kasper) tell me to install any software can make me choose the external port and the local port and the private address in my network to access any computer in the network not just the main one .. and how can i still protected from hackers ( i meant not to make ports opened in stupid way)

You may be best using an application lije 'LogMeIn'.

Kapersky cannot function as a router. You would need hardware for this. You can get routers that will allow your 3G card to connect.
In Kaspersky you need to open port 3389, Kaspersky already has a default rule for it so open Kaspersky main screen, on left hand side click on "system security", under firewall (middle of screen) click settings next to "network packets" then click on "Add", make sure allow is selected and under network service if you scroll down you can see "remote desktop", just add the rule then ok and you should be all set.
