Description
To enable a firewall protection, select Enabled. The
default is Enabled.
Prevents 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 prevents local clients from accessing local
services through active port forwarding rules (i.e. local
clients cannot use the router's public IP address to
access local services, as they might if they were
connected through the Internet). This feature does not
prevent a local client from accessing a local service
directly by using private addressing. This filter is
disabled by default. Select Enabled to filter Internet NAT
redirection, or Disabled to disable it.
Prevents port 113 from being scanned by devices
outside of your local network. This filter is enabled by
default. Select Enabled to filter port 113, or Disabled to
disable it.
Protects the SRP from Denial-of-Service attacks.
Use of WAN proxy servers can compromise your
network security. Enabling the proxy filter blocks access
to any WAN proxy servers. To enable proxy filtering,
check the box. This filter is disabled by default.
