Some on-line games (for example: Half Life) will use lots of fragmented UDP packets to
transfer game data. Instinctively as a secure firewall, Vigor router will reject these fragmented
packets to prevent attack unless you enable "Accept Incoming Fragmented UDP Packets". By
checking this box, you can play these kinds of on-line games. If security concern is in higher
priority, you cannot enable "Accept Incoming Fragmented UDP Packets".
