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 large incoming
fragmented UDP or ICMP 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 large
incoming fragmented UDP or ICMP Packets".
