I am attempting to use a p166 with two CNet C600e nics to network two other pcs with 3com elinkII 3c509b nics. I crossover between the nic pairs...pc2 3com to pc1 CNet and pc3 3com to pc1 CNet. I am not using a hub or switch. All machines are ME os and include tcp/ip, netbeui, and ipx bindings. I can get only one pair to work at a time, ie. pc1 to pc2 or pc1 to pc3. I cannot get pc2 and pc3 to see the other or to share. Machines are presently set to netbeui for their specific nic. Do I need a SW bridge between the two pc1 nics?
