OFP: Resistance uses UDP port 2302 by default. Compared to old OFP versions, this will resolve some compatibility problems that used to occur when running with Internet Connection Sharing (ICS). Also, the default query port is now UDP port 2303. If an OFP server host selects a different port for their server, the query port used is the selected server port number plus one.
While OFP MP beta versions 1.5X and 1.60 made use of UDP port 2314, OFP: Resistance does not.
