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”.
