Type the login name assigned by your ISP for this remote node.
Select this check box if your ISP assigned you a fixed IP address, 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 ZyWALL, not the remote router.
Leave this field set to 0.0.0.0 (default) to have the ISP or other remote router
dynamically send its subnet mask if you do not know it. Type the remote
gateway's subnet mask here if you know it (static).
Leave this field set to 0.0.0.0 (default) to have the ISP or other remote router
dynamically (automatically) send its IP address if you do not know it. Type the
remote gateway's IP address here if you know it (static).
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. Select SUA Only or None.
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 ZyWALL will
use Address Mapping Set 255 (see your User's Guide for more information).
Select None to disable NAT.
Select this check box to turn on RIP (Routing Information Protocol), which allows
a router to exchange routing information with other routers.
The RIP Version field controls the format and the broadcasting method of the
RIP packets that the ZyWALL sends (it recognizes both formats when receiving).
Choose RIP-1, RIP-2B or RIP-2M.
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.
