Please help me, I am new to theses things and have some questions that I am sure (hope) are very simple (Please make the answer simple as well).
 
I have an ISP that has given me a permenent IP number (well they say it may change once a week). My modem is atached to a zyxel 310 router and then to a hub with 3 pcs (2x win 98 1x w2k).
 
First question is my router a firewall?
 
2nd question how do I find out the IP number of the router (set to obtain an IP number automatically).
 
3rd question how do i let other people see and join a quake3 server on one of the pcs (i can find out the ip number of the pc server that the router gave it by pinging the computer name).
 
4th and final question, sometimes I get network inturuptions when playing quake or unreal online, can anyone tell me where to find out how to optimise the router or modem to reduce the interuptions (I dont know if itis the router or modem I should be playing with)
 
thanks to anyone who can help
