Login Server IP
Address Type the authentication server IP address here if your ISP gave you one.
This field is not available for Telia Login.
Login Server
(Telia Login only) Type the domain name of the Telia login server, for example login1.telia.com.
Relogin
Every(min)
(Telia Login only) The Telia server logs the ZyWALL out if the ZyWALL does not log in periodically.
Type the number of minutes from 1 to 59 (30 default) for the ZyWALL to wait
between logins.
WAN IP Address
Assignment
Get automatically
from ISP Select this option If your ISP did not assign you a fixed IP address. This is the
default selection.
Use Fixed IP
Address Select this option If the ISP assigned a fixed IP address.
My WAN IP
Address Enter your WAN IP address in this field if you selected Use Fixed IP Address .
My WAN IP
Subnet Mask Enter the IP subnet mask (if your ISP gave you one) in this field if you selected Use
Fixed IP Address .
Gateway IP
Address Enter the gateway IP address (if your ISP gave you one) in this field if you selected
Use Fixed IP Address .
Advanced Setup
Enable NAT
(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).
Select this check box to enable NAT.
RIP Direction RIP (Routing Information Protocol) allows a router to exchange routing information
with other routers. The
RIP Direction field controls the sending and receiving of
RIP packets.
Choose
Both , None , In Only or Out Only .
When set to Both or Out Only , the ZyWALL will broadcast its routing table
periodically.
When set to
Both or In Only , the ZyWALL will incorporate RIP information that it
receives.
When set to
None , the ZyWALL will not send any RIP packets and will ignore any
RIP packets received.
By default,
RIP Direction is set to Both .
RIP Version 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. By default, the
RIP Version field is set to RIP-1 .
Enable Multicast Select this check box to turn on IGMP (Internet Group Management Protocol).
IGMP is a network-layer protocol used to establish membership in a Multicast
group - it is not used to carry user data.
