lan port filter setup menu
the lan port filter setup menu allows you to apply filter sets to control your ethernet traffic.
filters are used to block certain packets, to reduce traffic, and to prevent security breaches. you must first create these filter sets using menu 21, and then apply them by number in this menu.
refer to chapter 10, 揅onfiguring filters,?for more information about configuring and applying filters.
table 7-4 lists and describes the interface and filter choices in the lan port filter setup menu.
table 7-4. menu 3.1 - lan port filter setup fields
tcp/ip and dhcp setup
the model rp114 router has the capability to act as a dhcp server, allowing it to assign ip, dns, and default gateway addresses to attached pcs or workstations. the assigned default gateway address is the lan address of the router, as set in the tcp/ip section. each pool address is tested efore it is assigned to avoid duplicate addresses on the lan.
if you are setting up your network for the first time, read about ip addresses starting with “ip addresses and the internet”?on page b-2 and “ip configuration by dhcp”?on page b-10 for an explanation of dhcp and information about how to assign ip addresses for your network.
for most applications, the default dhcp and tcp/ip settings of the router are satisfactory. these default settings are:
1?lan ip address 192.168.0.1 with subnet mask 255.255.255.0.
2?dhcp server enabled with 32 client addresses starting from 192.168.0.1.
3?dns proxy enabled (the router address is assigned as a dns server).
table 7-5 lists and describes the fields to use for setting up tcp/ip and dhcp parameters in menu 3.2. when you finish entering information in all of the fields, press [enter] at the prompt press enter to confirm. your selections are saved. press [esc] at any time to cancel the entries you have made.
if you change the lan ip address of the router while connected through telnet, you lose the telnet session. you must then open a new telnet connection to the new ip address and log in again.
