6.3.1.1 Firewall
The Network > Firewall screen allows you to customize port services for common applications. When
users send these types of requests to your network via the Internet, the GridRouter will deny or allow
those requests and, if enabled, forward them to the appropriate devices. Before using forwarding you
should assign static IP address to the designated devices. Refer to the DHCP page, section 6.2.5.6, for
more information on assigning static IP addresses.

Incoming Ports
Incoming ports are used to allow access to the GridRouter itself, not devices connected to the
GridRouter. An example would be querying SNMP information from the GridRouter. To allow/deny a
single port, enter the information on each line for the criteria required. The IP address “
0.0.0.0
” can be
used to denote any address.

Port Forwarding
Port forwarding is used to allow access to devices connected to the GridRouter. An example would be
accessing a device connected to the Ethernet of the GridRouter. To forward a single port, enter the
information on each line for the criteria required. The IP address “
0.0.0.0
” can be used to denote any
address.
