I wonder if my ISP will try to block my aMule port, so the network speed became slowly.
I suggest aMule to add a 'Dynamic TCP Port' feature, that user can define a port range (ex. 12000~15000), and ask aMule to select one port as the listen port each time we launch aMule (maybe set UDP port=TCP Port+10 and server UDP Port=TCP Port+3 automatically).
That should be useful if ISP or network administrator try to block aMule port.
