I picture something like this: -------------- | cablemodem | -------------- | --------- | HUB | --------- / \ --------- -------- | Win98 | | FBSD | --------- -------- Can you clarify? What I'm missing is the addresses, dhcp servers, their ranges, if your cable-account provides more than one address, and if your cablemodem is really just stuck into the hub as a peer or if there's some kind of gateway involved. You get the idea. Maybe you could provide more information about the topology? I probably don't need to say don't post real addresses. Still, it would be good to know of any routing or subnets or... Oh, and has it ever worked right, and if so, what changed? -Dave On Tue, 8 Feb 2000, Bob wrote: > Okay, here's the situation > > 1) I'm running 3.4-stable, cvs'd about a week ago > 2) I have a cable modem for my upstream > 3) I have a bsd box with a static IP, running an SMP kernel with 2 > processors > 4) I have a windows 98 box running dhcp, pulling it's IP from a > different network than the one my static IP is on > 5) these machines plug into a hub, not each other. the cable modem > is the uplink. > > I have periods of time (about 10-15 minutes each, usually) where my BSD > box just completely loses it's connection (it can't ping it's gateway, > which is one hop down the line, across the cable modem).
