5.4.2 WAN

You can configure the WAN port parameters on this page.
First, please choose the WAN Connection Type (Dynamic IP/Static IP/PPPoE/802.1X + Dynamic
IP/802.1X + Static IP/Big Pond Cable/L2TP/PPTP) for Internet. The default type is 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.
1. If you choose Dynamic IP, the router will automatically get IP parameters from your ISP.
You can see the page as follows (Figure 5-4):
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.
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.
