MTU
The Maximum Transmission Unit size may be
changed if you want to optimize efficiency for
uploading data through the WAN interface. The
default setting (1400 bytes) should be suitable for
most users. Some user may want to adjust the
setting to optimize performance for wireless traffic or
when low latency is desired (such as with Internet
gaming). It is highly recommended that the user
research how adjusting the MTU may affect network
traffic for better or worse.
MRU
Similar to the MTU, except this applies to Maximum
Received Unit size for downloading data. Most users
will be happy with the default setting (1492 bytes).
However this may also be optimized for fast
downloads of general bulk Internet traffic, for low
latency or for downloading to computers on the
Wireless LAN. As with the MTU setting, the user
should carefully consider how changing the MRU may
effect Internet downloads for all systems on your
LAN.
Default Route
When this is enabled, the Router will be considered
to be the primary gateway to the Internet and WAN
for systems on your network. If you are using the
Router on a network with one or more alternative
gateway routers, you may prefer to disable this if
you will use another router as the primary gateway.
NAT
Network Address Translation may be enabled or
disabled with the pull-down menu. Keep in mind that
disabling NAT allows only a single computer to be
used for Internet access through the Router. NAT is
enabled for the Router on all connections (i.e. Pvc0 –
Pvc7) if your Router is set up for multiple virtual
connections.
Firewall
Use this to universally enable or disable the Firewall
and Filter features available in the Router. If you
disable this you will not be able to configure settings
in the Firewall or Filters menus in the Advanced
directory.
IP Control
This is used to determine how global IP settings are
handled for the WAN interface. Typically PPPoE or
PPPoA connections will use the default setting for
Dynamic IP. Some users will be given a specific IP
address for the WAN interface. In this case you need
to change this setting to Static IP. When Static IP is
selected in the IP Control menu, you need to type in
