Dynamic IP. If you aren't given any login parameters (fixed IP Address, logging ID, etc),
please select Dynamic IP. If you are given a fixed IP (static IP), please select Static IP. If you
are given a user name and a password, please select the type of your ISP provided
(PPPoE/BigPond/L2TP/PPTP). If you are not sure which connection type you use currently,
please contact your ISP to obtain the correct information.

This page displays the WAN IP parameters assigned dynamically by your ISP, including IP
address, Subnet Mask, Default Gateway, etc. Click the Renew button to renew the IP
parameters from your ISP. Click the Release button to release the IP parameters.
MTU Size - The normal MTU (Maximum Transmission Unit) value for most Ethernet
networks is 1500 Bytes. For some ISPs you 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.
Use These DNS Servers - If your ISP gives you one or two DNS addresses, select Use
These DNS Servers and enter the primary and secondary addresses into the correct fields.
Otherwise, the DNS servers will be assigned dynamically from your ISP.
Note:
If you get address and find error when you go to a Web site, it is likely that your DNS servers are
set up improperly. You should contact your ISP to get DNS server addresses.
