Description
Select Enabled to use a firewall, or Disabled to disable
it.
When enabled, this feature keeps your network from
being "pinged," or detected, by other Internet users. It
also hides your network ports. Both make it more
difficult for outside users to enter your network. This
filter is enabled by default. Select Disabled to allow
anonymous Internet requests.
This feature uses port forwarding to block access to
local servers from local networked computers. Select
Enabled to filter Internet NAT redirection, or Disabled to
disable this feature.
This feature keeps port 113 from being scanned by
devices outside of your local network. Select Enabled to
filter port 113, or Disabled to disable this feature.
