Ok heres the situation
I have two computers on a network. They are also sharing the same wireless internet connection (but the network and the internet are separate). However, the computer I use is not the one hosting the wireless internet, but it is the computer which has most internet using programs on (games, msn, xfire, skype etc.). The problem is, now that we have a wireless router, I cannot use many of these programs properly due to the ports not being open. However, because there are two computers on the network and it is the other computer hosting it I am unsure of how to open the ports to make it work (ie. which IP to use). Also, I am unsure if windows firewall (which is active on both computers) might be blocking programs running on this computer despite the fact that MY windows firewall allows it, as it is the other computer, which does not run the same programs, that hosts the internet.
With me so far?
Basically I have looked everywhere but I need to know if firstly windows firewall on the other computer is affecting this, and if so do I simply have to open the ports on the firewall, and secondly how to configure my router to open the ports on MY computer, even though the OTHER computer is running the internet.
If anyone could offer advice i'd be eternally grateful
