TL-R600VPN
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.
Primary DNS & Secondary DNS - 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 ISP.
Host Name – This option specifies the host name of the router.
Note:
If you get 'Address not found' errors 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 correct DNS server.
Get IP with Unicast DHCP: A few ISPs' DHCP servers do not support the broadcast
applications. If you can not get the IP address normally, you can choose this option. (You
don't need select this option generally).
