Vigor2110 Series User’s Guide

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
”.
