DESCRIPTION

 

 

Administrator

Type how many minutes a management session (either via the web

Inactivity Timer

configurator or SMT) can be left idle before the session times out.

 

The default is 5 minutes. After it times out you have to log in with your

 

password again. Very long idle timeouts may have security risks.

 

A value of "0" means a management session never times out, no matter how

 

long it has been left idle (not recommended).

System DNS Servers

 

 

 

First DNS Server

Select From DHCP if your DHCP server dynamically assigns DNS server

Second DNS Server

information (and the ZyAIR's Ethernet IP address). The field to the right

displays the (read-only) DNS server IP address that the DHCP assigns.

Third DNS Server

Select User-Definedif you have the IP address of a DNS server. Enter the

 

 

DNS server's IP address in the field to the right. If you chose User-Defined, but

 

leave the IP address set to 0.0.0.0, User-Definedchanges to None after you

 

click Apply. If you set a second choice to User-Defined, and enter the same IP

 

address, the second User-Definedchanges to None after you click Apply.

 

Select None if you do not want to configure DNS servers. If you do not

 

configure a DNS server, you must know the IP address of a machine in order to

 

access it.

 

The default setting is None.

4.3 Dynamic DNS

Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also access your FTP server or Web site on your own computer using a domain name (for instance myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don't know your IP address.

First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a domain name. The Dynamic DNS service provider will give you a password or key.

4.3.1 DynDNS Wildcard

Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname.

Note: If you have a private WAN IP address, then you cannot use Dynamic DNS.
