Hi Jubal,

Greetings,

Is there a general how-to, or a set of coherent instructions, for shaping outbound traffic such that when I upload something over my asymmetric cable-modem pipe, doing so doesn't completely kill my Web browsing or any other attempts to use my Internet connection?

(To put it another way: When I max out my upstream, and my upstream is capped lower than my downstream, my downstream becomes useless and I am forced to wait until the upload finishes before I can resume using the downstream. This is a problem, and I'd like to solve it.)

I have looked at various ALTQ + pf setups on the Web, but I have one caveat. I use FreeBSD 6.4 on my home gateway, and it is also using the default natd server, which relies on an ipfw divert rule. I don't know if this matters, or if I need to switch from natd to a pf-based NAT setup.

Technically you could run both, for a while years back I was using pppd's nat, ipfw for the firewall and dummynet (for kids downloads and stuff or when they reached their monthly quota), and pf for altq on outbound.

All working perfectly.



Should I use *just* ipfw, or should I switch everything to pf (including NAT services) and go from there?

Thanks much,

Jubal
