FIELD DESCRIPTION
IP Address
Assignment
If your ISP did not assign you an explicit IP address, press [SPACE BAR] and then
[ENTER] to select Dynamic ; otherwise select Static and enter the IP address &
subnet mask in the following fields.
(Rem) IP
Address
If you have a static IP Assignment, enter the IP address assigned to you by your ISP.
(Rem) IP
Subnet Mask
If you have a static IP Assignment, enter the subnet mask assigned to you.
Gateway IP
Addr
This field is applicable to Ethernet encapsulation only. Enter the gateway IP address
assigned to you if you are using a static IP address.
My WAN Addr This field is applicable to PPPoE and PPTP encapsulations only. Some
implementations, especially the UNIX derivatives, require the WAN link to have a
separate IP network number from the LAN and each end must have a unique
address within the WAN network number. If this is the case, enter the IP address
assigned to the WAN port of your ZyXEL device.
Note that this is the address assigned to your local ZyXEL device, not the remote
router.
Network
Address
Translation
Network Address Translation (NAT) allows the translation of an Internet protocol
address used within one network (for example a private IP address used in a local
network) to a different IP address known within another network (for example a public
IP address used on the Internet).
Choose
None to disable NAT .
Choose SUA Only if you have a single public IP address. SUA (Single User Account)
is a subset of NAT that supports two types of mapping: Many-to-One and Server .
Choose Full Feature if you have multiple public IP addresses. Full Feature mapping
types include: One-to-One , Many-to-One (SUA/PAT), Many-to-Many Overload ,
Many- One-to-One and Server . When you select Full Feature you must configure at
least one address mapping set!
See the
NAT chapter for a full discussion on this feature.
Metric Enter a number from 1 to 15 to set this route’s priority among the ZyXEL device’s
routes (see the Metric section in the WAN and Dial Backup Setup chapter) The
smaller the number, the higher priority the route has.
Private This field is valid only for PPTP/PPPoE encapsulation. This parameter determines if
the ZyXEL device will include the route to this remote node in its RIP broadcasts. If
set to Yes , this route is kept private and not included in RIP broadcast. If No , the
route to this remote node will be propagated to other hosts through RIP broadcasts.
RIP Direction Press [SPACE BAR] and then [ENTER] to select the RIP direction from Both / None /
In Only / Out Only . See the LAN Setup chapter for more information on RIP. The
default for RIP on the WAN side is None . It is recommended that you do not change
this setting.
Version Press [SPACE BAR] and then [ENTER] to select the RIP version from RIP-1 / RIP-2B /
RIP-2M or None .
Multicast IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a Multicast group. The ZyXEL device supports both IGMP
version 1 ( IGMP-v1 ) and version 2 ( IGMP-v2) . Press [SPACE BAR] to enable IP
Multicasting or select None to disable it. See the LAN Setup chapter for more
information on this feature.
Once you have completed filling in Menu 11.3 Remote Node Network Layer Options , press [ENTER]
at the message “Press ENTER to Confirm...” to save your configuration and return to menu 11, or press
[ESC] at any time to cancel.
