Now, I have a cable modem, but in this area, they're still using those lame hybrid (downstream through cable modem, upstream through analog modem and PPP) setups. I suspect that with some clever use of natd, ipfw, et. al. the connection can still be shared, but I'm stymied. Here's the situation I have a computer with ed0 connected to the ApartmentNet (TM). The cable modem is connected to an ethernet interface xl0, but that's only downstream. Upstream is through a PPP connection on tun0. Can anyone more skilled in IP than I (not saying much) suggest any incantations to natd'ize the cable modem connection? Let me know if I need to provide any more info, tcpdump(1)s, etc. Lucas -- S.
