Filters - D-Link DSL-G604T User Manual

Filters

The following window will aid the router's administrator in configuring filters for IP addresses. There
are two types of filters that the administrator can configure. Outbound Filters are for administrators
who wish to deny clients on their LAN from accessing certain virtual ports or IP addresses on the
Internet. Inbound Filters are for administrators who wish to deny IP addresses or virtual ports from
outside the router (on the Internet) from accessing the Internal LAN of the router. Click the
corresponding radio button to configure Outbound or Inbound Filters. Both screens are identical in
configuration.
To configure filters for the router, configure the folowing fields and click Apply.
