And yes, it's ipaddress is mwm.tzo.com. But I didn't stay working with Unix on x86 until the PIII was around, so I don't have lots of old boxes. Well, I could try and resurrect a Sun 3 and find another ethernet card for it, but... > On a picky note with a guess, your box's interface is set to netmask > 0xffffff00 while the hub/router is netmask 0xffff0000 if it is 192.168 > based.

The router has a LAN side netmask of 0xffffff00. Like I said, I'm pretty sure it's restricted to the 192.168.1. addresses internally. But I can set it's LAN side IP address and netmask to whatever I want. > I'm not sure what's happening Mike. IPFW getting in the way? I'm not sure anything is wrong in my setup - except I'm confused about my inability to force half duplex. My network seems to be fine. I just saw the note about "run half duplex to hubs", and wondered if I was getting all I could out of my network.
