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".
Check this box to enable transparent function for such router. It
is not necessary for users to re-organize the network or configure
the subnet settings for each PC connected under such router.
However, the configured Anti-Virus and Anti-Intrusion profiles
can be applied to PCs connected behind vigor router to have the
best security. The following picture explains the basic structure
for using transparent mode for vigor router.
PCs with subnet "172.16.x.x" connected under VigorPro 5510
will be protected by security settings enabled and configured on
the web pages of Vigor router. When the transparent mode has
been checked, hackers from Internet do not sense the existence of
vigor router, therefore they cannot attack the router.
