The port FastTrack will listen on for incoming connections. Both TCP and UDP.
If you are behind a NAT and you are forwarding the above port you have to enable this i.e. you forward outside_ip:port -> inside_ip:port outside_ip and inside_ip are determined automatically. Do not enable this if you are not forwarding.
If enabled FastTrack will share files as configured with giftd. If disabled files will never be shared on FastTrack even if giftd shares on other networks.
If enabled FastTrack will filter out all search results which come from ips matching the ranges specified in the file AMIGIFT:daemon/FastTrack/banlist
If Enabled FastTrack will automatically search again after a search has completed.
