• 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.
MTU Size
The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is 1500 Bytes. For
some ISPs, particularly some using PPPoE, you may need to reduce the MTU. This is rarely
required, and should not be done unless you are sure it is necessary for your ISP connection.
Any packets sent through the firewall that are larger than the configured MTU size will be
repackaged into smaller packets to meet the MTU requirement. To change the MTU size:
1. Under MTU Size, select Custom.
2. Enter a new size between 64 and 1500.
3. Click Apply to save the new configuration.
Note: If you change the LAN IP address of the firewall while connected through the
browser, you will be disconnected. You must then open a new connection to the new IP
address and log in again.
