Something like: ipfw add 1000 pipe 80 tcp from <ppp network> to any 80 out via <lan nic> For individual ppp users/connections the options are probably(I haven't done any of this): 1) assign general traffic shaping pipe to ppp interfaces by specifying the interface with the firewall rule (e.g. ipfw add 1000 pipe 100 ip from any to any via ppp0) 2) assign static addresses to the users and adjust rules as needed 3) dynamically add&remove rules... I'll guess as part of ppplogin script I'm not sure there is much value in applying traffic shaping rules/pipes to individual ppp interfaces. The total available bandwidth for each ppp connection is pretty low and it is already dedicated to just that one user anyways.
