DESCRIPTION

 

 

DMZ TCP/IP

 

 

 

IP Address

Type the IP address of your Prestige’s DMZ port in dotted decimal notation. Make

 

sure the IP address is on a separate subnet from the LAN port.

IP Subnet Mask

The subnet mask specifies the network number portion of an IP address. Your

 

Prestige will automatically calculate the subnet mask based on the IP address

 

that you assign. Unless you are implementing subnetting, use the subnet mask

 

computed by the Prestige 255.255.255.0.

RIP Direction

RIP (Routing Information Protocol, RFC1058 and RFC 1389) allows a router to

 

exchange routing information with other routers. The RIP Direction field controls

 

the sending and receiving of RIP packets. Select the RIP direction from Both/In

 

Only/Out Only/None. When set to Both or Out Only, the Prestige 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. Both is the default.

RIP Version

The RIP Version field controls the format and the broadcasting method of the

 

RIP packets that the Prestige sends (it recognizes both formats when receiving).

 

RIP-1 is universally supported but RIP-2 carries more information. RIP-1 is

 

probably adequate for most networks, unless you have an unusual network

 

topology. Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the

 

difference being that RIP-2B uses subnet broadcasting while RIP-2M uses

 

multicasting. Multicasting can reduce the load on non-router machines since they

 

generally do not listen to the RIP multicast address and so will not receive the

 

RIP packets. However, if one router uses multicasting, then all routers on your

 

network must use multicasting, also. By default, RIP direction is set to Both and

 

the Version set to RIP-1.

Multicast

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to

 

establish membership in a multicast group. The Prestige supports both IGMP

 

version 1 (IGMP-v1) and IGMP-v2. Select None to disable it.
