I just got two home PCs connected to each other over a 5-port switch with. 10.0.0.100 and 10.0.0.101 (this one). I set this as the gateway because a while later when I hook this to the web, this will be the box. And I might add a couple of more boxes to this network at best. I did not set a gateway in /etc/rc.conf. I configured the whole thing using sysinstall and a couple of times after that using ifconfig (ip addr and netmask). > > defaultrouter="your gateway ip address" # Set to default > gateway (or NO).

That's a choice ... I am not sure I can offhand say if that's the correct choice or not. With the eventual size of my network that I can anticipate, I could even set it to 255.255.255.192 may be. How do you find out the duplex setting :P (terribly ashamed of my newbiness). I guess it is full duplex under both. > > Bob > > Cheers, Andy
