I've got an old Netopia router from my ISP (SBC now AT&T) and I've got 5 static IP's from them. I want to set up two networks in my office: one for workong on customer's computers and another netowrk for my office LAN. I do not want packets to be able to travel betweeen these networks; I want my office LAN to be totally unreachable from the other network.
What I need to know is simply where I need to place a router, firewall, or whatever to accomplish this isolation. I've got plenty of switches lying around so equipment is no problem. I"ll buy whatever I need to buy regarding another router, firewall, or whatever I need to get in order to accomplish my goal. Make sense? Help please. Thanks.
