Packet Size (MTU). The Maximum Transmission Unit of an IP packet. The default value is
1492 Bytes. If your ISP requires a special value, please select from the pull down menu. The
default value will work for most cases. Otherwise, contact your ISP for the MTU value.
Disconnect after idle time. The PPPoE connection will be disconnected by the gateway
automatically when there is no Internet traffic for the idle time specified. The idle time of “0”
means an always-on connection. The default value is “0” minute.
Enable Unnumbered PPP Connection. Check this box and enter the IP address of the
unnumbered connection. Contact your ISP if you are unsure if this feature is required for your
PPPoE connection.
Use Static DNS. If you want to use your own DNS instead of the one provided by your ISP,
click the checkbox and type the IP address of the DNS in the field. (At least one for the
primary field.)
MAC address. Some ISPs allow you to connect to them with a specified MAC address only.
You can enter the MAC address manually or copy it from a PC which is attached to the Local
Port. Simply type in its IP address and the gateway will copy the MAC address from that PC.
The gateway comes with the factory default MAC address. You do not need to change the
default value if the ISP is not checking the MAC address of your Internet Port.
