RAC2V1A Router User Guide 65
Application layer gateway settings allow the router to recognize and
treat certain network protocols specially.
Important: You should not change these settings unless recommended
by your service provider. Most users will never need to change the
settings on this page.
Application Layer Gateway
Click the checkbox for each network protocol for which you want
special handling. Options are IPSec, PPTP, PppoePassthrough,
IpsecPassthrough, PptpPassthrough, and L2tpPassthrough.
MAC Filter
MAC address filtering gives you an extra layer of security by allowing
you to specify which devices can access your network. Whenever a new
device tries to join your network, the router checks the MAC address of
the device against a list of approved addresses. You can choose to allow
(whitelist) or deny (blacklist) MAC addresses. Whenever a device tries
to access your network, the router checks the MAC filter settings to
determine whether the device should be allowed to access your
network.
