I have htb on 486 sx with 16mb ram. Slackware 9.1. Connection : dsl 1Mbit.
486 works as router and trafic shaper for network made of 12 pc's. it does the job quite well, but when i play Counter-Strike or connect to my 486 via ssh (on lan), i get huge lag every 11-20 sec. when i connect to 486 via ssh and run iptraf program i see all the trafic, and after a while when lag comes the kb/s stats reset. and iptraf shows that there is only 50% bandwith usage. What could be the problem ?
