Q1: What is the best way to prevent arp flux when running HTB 3.6 on 2.4.20 with static route patch? I've got one nat'ed LAN and four ADSL interfaces and all five interfaces have a HTB qdisc Q2: When a cllient on LAN downloading/uplloading something from/to internet I can see that cllient consuming bandwidth on all ADSL interfaces in iptraf. Is this a bug in IPtraf or is it actually using bandwidth on all interfaces? If it does, how do I prevent this? Does it have to do with arp flux? Kjell
