RIP Direction
 
RIP (Router Information Protocol) allows a router to exchange routing information with other 
routers. The RIP Direction selection controls how the firewall sends and receives RIP packets. 
Both is the default. 
— When set to Both or Out Only, the firewall will broadcast its routing table periodically. 
— When set to Both or In Only, it will incorporate the RIP information that it receives. 
— When set to None, it will not send any RIP packets and will ignore any RIP packets 
received. 
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. 
— RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you 
have an unusual network setup. 
— RIP-2 carries more information. Both RIP-2B and RIP-2M send the routing data in RIP-2 
format. 
— RIP-2B uses subnet broadcasting. 
— RIP-2M uses multicasting.
Using the Router as a DHCP Server
By default, the firewall will function as a DHCP (Dynamic Host Configuration Protocol) server, 
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to 
the router's LAN. The assigned default gateway address is the LAN address of the firewall. IP 
addresses will be assigned to the attached PCs from a pool of addresses specified in this menu. 
Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the firewall are satisfactory. See 
 for an explanation of DHCP and information about how 
to assign IP addresses for your network. 
Note: 
Multicasting can reduce the load on non-router machines because they do not 
listen to the RIP multicast address and will not receive the RIP packets. However, if one 
router uses multicasting, then all routers on your network must use multicasting.
