The LAN FIREWALL SET-UP MENU contains menu options to control the IP firewall settings for LAN connections
to this device. The LAN FIREWALL SET-UP MENU and WAN FIREWALL SET-UP MENU contains identical
menu options. They control the IP firewall settings for LAN and WAN connections to this device.
Note: If an optional second LAN interface installed, you will be requested to select which LAN interface is to be
configured before proceeding.
Remember that when the firewall function is set to both, all incoming and outgoing IP traffic to and/or from the LAN
interface (including secondary LANs) will be filtered. All IP traffic(TCP, UDP (ping), TFTP and PPP) received from or sent
to the LAN(s) will be filtered out and not allowed through the firewall.
To allow specific IP traffic to be passed between another network connection and this LAN, either a firewall entry must be
specified or a designated server must be specified or a combination of the two. The direction in which the firewall is to filter
traffic (inbound, outbound or both) is specified under the Firewall option (3) or may be set on an individual firewall table entry
basis via the Edit firewall entry option (2).
1 - Designated Servers
The Designated Servers option directs you to the Designated Servers Menu, where the IP addresses may be defined for
the designated servers on the LAN. A designated server is a device that is legally accessible from another network
connection. An example, designated servers may be the HTTP server and the FTP server on the LAN that may be
accessed by devices located at remote sites.
2 - Edit Firewall Entry
This option directs you to the Edit Firewall Entry Menu, where a table of entries that are to be allowed to pass IP traffic
through the firewall is defined. The Firewall table may have up to 128 entries.
3 - Firewall
The Firewall option controls the direction in which Firewall filtering is to be applied by this P1700 to all traffic through
the LAN interface.
By default, the direction in which filtering will be applied for all entries in the firewall table is initially set to the direction
specified by this option. This direction may be changed for individual entries using the Edit firewall entry option (2). Once
the direction of filtering for some entries has been altered, changing the overall direction applied to the firewall table will
not affect those entries that have been changed; if a change to these entries is required, each entry that needs to be
changed must be edited individually.
