WAN Service Setup 50
Model 3101 Series Getting Started Guide 5 • Advanced Configuration
– PPP Username: The valid username provided by your ISP.
– PPP Password: The valid password provided by your ISP.
– Authentication Method: Select from AUTO, PAP, CHAP, MSCHAP. (Default = AUTO)
– Enable Fullcone NAT: With NAT, all requests from the same internal IP address and port are mapped
to the same external IP address and port. Furthermore, any external host can send a packet to the inter-
nal host, by sending a packet to the mapped external address.
– Dial on demand (with idle timeout timer): If enabled, enter the Idle Timeout value in minutes. If the
3101 doesn’t detect the flow continuously within the allotted time, the unit will automatically discon-
nect the PPPoA connection. Once it detects the flow (such as access to a webpage), the 3101 will restart
the PPPoA connection. If disabled, the 3101 will perform PPPoA dial-up all the time. Unless the 3101
is powered off and DSLAM or uplink equipment are operating abnormally, the PPPoA connnection will
stay up.
– Use Static IPv4 Address: If enabled, the 3101 uses this IP as the WAN IP address. If disabled, the 3101
obtains an IP address assigned through uplink equipment.
– Enable PPP Debug Mode: Enable or disable this function.
– Enable IGMP Multicast Proxy: Enable this function if you want PPPoA mode to support IPTV.
