Reference Manual for the Model DG824M Wireless ADSL Modem Gateway
6-4 Advanced Configuration
The LAN TCP/IP Setup parameters are:
• IP Address
This is the LAN IP address of the gateway.
• IP Subnet Mask
This is the LAN Subnet Mask of the gateway. 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.
• RIP Direction
RIP (Router Information Protocol) allows a router to exchange routing information with other
routers. The RIP Direction selection controls how the gateway sends and receives RIP packets.
Both is the default.
— When set to Both or Out Only, the gateway 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
PPPoE, the gateway adjusts the MTU size automatically. Changing this is rarely required, and
should not be done unless you are sure it is necessary for your ISP connection.
Note: If you change the LAN IP address of the gateway 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.
