Host Name Some ISPs, usually cable ISPs, require a host name as identification.
You may have to check with your ISP to see if your broadband Internet service has
been configured with a host name. In most cases, leaving this field blank will work.
Domain Name Some ISPs, usually cable ISPs, require a domain name as
identification. You may have to check with your ISP to see if your broadband
Internet service has been configured with a domain name. In most cases, leaving
this field blank will work.
MTU MTU is the Maximum Transmission Unit. It specifies the largest packet size
permitted for Internet transmission. Select Manual if you want to manually enter
the largest packet size that will be transmitted. To have the router select the best
MTU for your Internet connection, keep the default setting, Auto.
Size When Manual is selected in the MTU field, this option is enabled. It is
recommended that you set this value within the range of 1200 to 1500, but the
value can be defined between 128 and 1500.
DDNS Service DDNS Service is disabled by default. To enable DDNS Service,
follow these instructions:
Sign up for DDNS Service
•
DynDNS - Sign up for DDNS service at
your User Name, Password, and Host Name information.
•
TZO - Sign up for DDNS service at
mail Address, Password and Domain Name information.
Select the DDNS service provider whose service you are using.
Configure the following fields:
•
User Name (DynDNS) or E-mail address (TZO).
•
Password
•
Host Name (DynDNS) or Domain name (TZO)
•
Custom DNS (DynDNS)
Click Save Settings.
The router will now advise the DDNS Service of your current WAN (Internet) IP
address whenever this address changes. If using TZO, you should NOT use the
TZO software to perform this "IP address update".
