I spent some time this morning looking at ip-up.local and its parameters. I can see I can get the pppX, local and remote ip numbers. My current thinking is that I just add a line to the script to 'add'/bind the new ip when the connection goes live, then add a line to ip-down.local to remove the rule when the link goes down. So how about this...?... # In ip-up.local tc qdisk add dev ppp<X> root handle 1:<X> htb tc class add dev ppp<X> parent 1:<X> classid 1:<X> htb rate 56kbit ceil 56kbit tc filter add dev ppp<X> parent 1:<X> protocol ip prio 1 u32 \ match ip dest <X-remoteIP> flowid 1:<X> How do I remove all this when the ppp connection goes off line?
