client port are random, if you want to use range, create one line in iptables on mangle for forward and mark that rule, whi that?
webhtb whan parse to /sbin/tc if you want to use in webhtb something like dst-ip`s: 1024:65535 , will be a pain in the ass, because TC don`t know that and webhtb must parse 65535 - 1024 lines for only that rule, so better use iptables to mark that range and on webhtb create one rule with that mark
