Hi, I have a 3Mbit (up,down) connection going through a Linux box (Debian 600mhz, 500mb ram) using NAT to approx 125 users. Presently I am shaping by marking packets by their port numbers. I'm prioritizing 22, 23, 25, 80, 81, 110, 443, 500, 3389, 1214, 6881:6889, etc, into their appropriate classes depending on weather there getting more or less bandwidth. This has worked pretty good, but some users have problems at times like time-outs browsing, email and such. One question, should I be using SFQ on these classes? Would this decrease the time-outs some users are getting at heavy load times? If so, could someone please explain what this (SFQ) does, as the documentation in the LARTC and other spots is very weak. Another question, I was also thinking of limiting everyone's bandwidth to like say 500K each, so no connection can get more then 500k, then it would take about 6 people using full connections to max the line. I have searched and found no real good way to do this other than creating 125 classes and filters AND if I did that would I still be able to perform QoS on certain ports. I'm confused on if this is possible or not for it seems that once you filtered a IP address for instance, then it's gone and cannot be filtered through another qdisc. Doing the math, if I had 125 users divided up into a 3mbit connection, I would have to have a rate of 24 kbps and ceil of 500kbps per class. But if I did rate limit each user, now how do I rate limit all the ports flowing as a whole like I was originally doing? Thanks for the help. -Dave _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
