Ahh yes .. so that maximum N is fixed in this way ? Hmmm and you then need way to map active connection to free class in HTB for example. It will not be simple because you can't say when conversation ends (safely). So that you will end with all classes busy. You would have to write it yourself probably - extend iptables connection tracking to maintain table of classids and select classid for new connection and return it when conn is deleted. Then simply copy this number to fwmark ... If you really need this and can't write it you could ask in lartc list whether someone is willing to write it (for fun or for money). devik On Tue, 10 Sep 2002, Michael O'Shea wrote: > devik, > But this is my problem - I don't want bw per connection = total/n ...
