• MTU Size : The normal MTU (Maximum Transmit Unit) value for most Ethernet networks is
1500 Bytes. For some ISPs you may need to reduce the MTU. But this is rarely required, and
should not be done unless you are sure it is necessary for your ISP connection.
Dynamic DNS
A Dynamic DNS Service provides a central public database where information (such as e-mail
addresses, host names and IP addresses) can be stored and retrieved. The Dynamic DNS server
also stores password-protected information and accepts queries based on e-mail addresses.
If you want to use a Dynamic DNS service, you must register for it. The Dynamic DNS client
service provider will give you a password or key.
To set up Dynamic DNS:
1. Select the Use a Dynamic DNS Service check box if you have registered with a DDNS
service provider.
2. Select the name of your dynamic DNS Service Provider.
3. Type the Host Name that your dynamic DNS service provider gave you.
The DDNS service provider may call this the domain name.
4. Type the User Name for your Dynamic DNS account.
5. Type the Password (or key) for your Dynamic DNS account.
6. If you have DYNDNS as your Dynamic DNS service provider, you can select the Use
Wildcards check box to activate this feature.
7. Click Apply.
