Figure 31: WAN-Dynamic IP
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. It is not recommended that you
change the default MTU Size unless required by your ISP.
◆ 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.
N OTE : If you find an error when you go to a Web site after entering the
DNS addresses, it is likely that your DNS servers are set up improperly. You
should contact your ISP to check the DNS server addresses.
◆ Get IP with Unicast DHCP - Some ISP DHCP servers do not support
broadcast applications. If you cannot get the IP Address normally, you
can choose this option. (It is rarely required.)
