the firewall is shipped preconfigured to use private ip addresses on the lan side, and to act as a dhcp server. the firewall’s default lan ip configuration is:

    1 lan ip addresses—192.168.0.1

    2 subnet mask—255.255.255.0

    these addresses are part of the ietf-designated private address range for use in private networks, and should be suitable in most applications. if your network has a requirement to use a different ip addressing scheme, you can make those changes in this menu.

    universal plug and play (upnp) helps devices, such as internet appliances and computers, access the network and connect to other devices as needed. upnp devices can automatically discover the services from other registered upnp devices on the network.

    upnp can be enabled or disabled for automatic device configuration. the default setting for upnp is disabled. if disabled, the router will not allow any device to automatically control the resources, such as port forwarding (mapping), of the router.

    the lan tcp/ip setup parameters are:

    1 ip address

    this is the lan ip address of the firewall.

    2 ip subnet mask

    this is the lan subnet mask of the firewall. combined with the ip address, the ip subnet mask allows a device to know which other addresses are local to it, and which must be reached through a gateway or router.

    3 rip direction

    rip (router information protocol) allows a router to exchange routing information with routers. the rip direction selection controls how the firewall sends and receives rip packets. both is the default.

    1 when set to both or out only, the firewall will broadcast its routing table periodically.

    2 when set to both or in only, it will incorporate the rip information that it receives.

    3 when set to none, it will not send any rip packets and will ignore any rip packets received.

    4 rip version

    this controls the format and the broadcasting method of the rip packets that the router sends. it recognizes both formats when receiving. by default, this is set for rip-1.

    1 rip-1 is universally supported. rip-1 is probably adequate for most networks, unless you have an unusual network setup.

    2 rip-2 carries more information. both rip-2b and rip-2m send the routing data in rip-format.

    1 rip-2b uses subnet broadcasting.

    2 rip-2m uses multicasting.

    if you change the lan ip address of the firewall while connected through browser, you will be disconnected. you must then open a new connection to the new address and log in again.
