Some on-line games (for example: Half Life) will use UDP packets with
large length to transfer data. These large UDP packets need to be
fragmented. As secure firewall, Vigor router will reject these kinds of
packets to avoid to be attacked by outside hackers if you do not enable
"Accept Incoming Fragmented UDP Packets". You can enable "Accept
Incoming fragmented UDP Packet" function to accept these kinds of
packets. Then you can play these kinds of on-line games. If you take
security concern as high priority, you shall disable "Accept Incoming
Fragmented UDP Packets". ‡
