FR> Just substitute 192.168.2.X for 0.X, in the example I provided earlier. -------Copied from prior message from Frank Reid-------- FR> Workgroup1 192.168.0.2 - 192.168.0.62 FR> Workgroup2 192.168.0.66 - 192.168.0.126 FR> Workgroup3 192.168.0.130 - 192.168.0.190 FR> Workgroup4 192.168.0.194 - 192.168.0.254 Ok let me get this strait in my mind. My local gateway on the router is 192.168.2.1. If I set up a computer with an address of 192.168.2.10 and a subnet mask of 255.255.255.192 it will see and communicate with all the machines setup with the same subnet mask and in the range of 192.168.2.2 through 192.168.2.62 and not see or communicate with the ones in the other ranges, but they all will communicate with the gateway at 192.168.2.1. Now I have my file sharing and print sharing setup on Netbios not tcp/ip. What does this throw in to the equation and affect what is seen and what is not. Now what about the addresses 192.1687.2.63/65 and 127/129 and 191/193. Is there some doc's or tables on what different subnet mask numbers do or how they affect network connections? .... Ben ....
