Hi, all --
I've successfully used natd to share a dialup connection among my
apartment's network for quite a while. 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.
