Ok i know this is a LAME question but i have searched netgears web page + yahoo and need help.

1) Can a netgear router be used to connect 2 computers togather in a network. (not just share a net connect but to use tcp/ip to play games such as counter strike and diablo 2

The two computers refuse to see each other in network hood.
Computer two can ping computer 1 but 1 cannot ping computer 2 and is stopped at the router.. We both share the same workgroup and have all of our TCP/IP settings set to let the computer decide what to be assigned to where.

I need any help that can be given on this very newbish topic PLZ
