I currently have a 10Base2 LAN consisting of 2 Winblows systems, one
FreeBSD/Windows system and one RedHat 5.2 system. The 5.2 box is a
Pentium 66 with 16MB of RAM and is currently using IP masquerading to
share a 56k-based modem connection (PPP) with the other systems.

Now, we're considering buying a cable modem, and I have determined
that I'll be able to get it working under linux. I'm planning on
upgrading the Pentium 66 to RedHat 6.2 and either running CBQ (Class
Based Queueing) or basic traffic shaping on it, so an individual user
can't hog the cable connection. (it's limited at 400kbit/s down,
128kbit/s up unfortunately).

My good ol' pentium has kept things going for a very long time and has
worked incredibly reliably, but my main question is -
What kind of a load would CBQ or traffic shaping put on a system like
this? Bear in mind there'll only be 4 systems on the LAN (including
the route/masqer/shaper itself).
Does anyone have an opinion on whether the Pentium will handle this
OK? Additionally, is packet shaping or CBQ known to work in
conjunction with IP masquerading?

Any info would be appreciated :-)

I've done a similar configuration. CBQ and Masq on a P75 with 640kb/up
128kb/down. With my 3 - 4 host network, the P75 was sufficient.

CBQ should work with masq, i had some trouble with u32 filters and
masq (posted an earlier message about this), but i've since got fwmark
filters work fine.
