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".
