DESCRIPTION
Type the login name assigned by your ISP for this remote node.
and then enter the IP address in the following field.
Leave the field set to 0.0.0.0 (default) to have the ISP or other
remote router dynamically (automatically) assign your WAN IP
address if you do not know it. Type your WAN IP address here if
you know it (static). This is the address assigned to your local
device, not the remote router.
Network Address Translation (NAT) allows the translation of an
Internet protocol address used within one network to a different IP
address known within another network.
SUA (Single User Account) is a subset of NAT that supports two
types of mapping: Many-to-One and Server. When you select this
option the device will use Address Mapping Set 255 in the SMT (see
the section on menu 15.1 for more information).
Select the check box to enable SUA. Clear the check box to disable
SUA so the device does not perform any NAT mapping for the dial
backup connection.
Select this check box to forward the backup route broadcasts to the
WAN.
Select this check box to turn on IGMP (Internet Group Multicast
Protocol). IGMP is a network-layer protocol used to establish
membership in a Multicast group - it is not used to carry user data.
Select IGMP-v1 or IGMP-v2. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is still
in wide use. If you would like to read more detailed information
about inter operability between IGMP version 2 and version 1,
please see sections 4 and 5 of RFC 2236.
Select this check box to turn on RIP (Routing Information Protocol),
which allows a router to exchange routing information with other
routers.
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 device broadcasts its
routing table periodically. When set to Both or In Only, it
incorporates the RIP information that it receives; when set to
None, it does not send any RIP packets and ignores any RIP
packets received. Both is the default.
