connected to your provider before terminating the connection. A non-zero value.
Set Defaultroute: Specify connection as the default-route.
MRU: Maximum Receive Unit the DSL connection can receive. It is an negotiated value that ask the
provider to send packets of no more than n bytes. The minimum MRU value is 128.
Enforce MRU: Check this box if you experience problems accessing the Internet over a PPPoE
connection. This feature will force all TCP traffic to conform with PPP MRU by changing TCP Maximum
Segment Size to PPP MRU.
Debug: Enables PPP connection debugging facilities.
Connect: Use the current settings to establish a ppp connection. In "On Demand" mode "Connect"

5. UPnP (Section 4.4.1 : ADVANCED – UPnP): Help pages for UPnP.
 UPnP NAT and Firewall Traversal allow traffic to pass-thru the router for applications using the
UPnP protocol. This feature requires one active DSL connection. In presence of multiple DSL
connections, select the one over which the incoming traffic will be present, for example the default
Internet connection.
6. IP QoS (Section 4.4.4 : ADVANCED - IP QoS): Help section for IP QoS.
 IP QoS services in the NSP is applicable to the output device (Egress side). Meaning the IP QoS
traffic shaping is associated with any transmitted traffic from the perspective of the NSP. Each
output device has 3 priority queues associated with transmit data. The High priority queue has
strict priority over medium and low priority queues. The Medium and Low priority queues are
serviced on a Round Robin priority basis according to the configured weights (WRR), after the
High priority queue has been completely serviced.
The "IP QoS" section under "Advanced section" allows you to setup IP QoS for a connection.
The "IP QoS" section has two sub-sections - QoS Setup Page and Rule Setup Page.
 QoS Setup Page
The QoS setup page allows you to configure IP QoS for a connection, to view the configured QoS
rules and to add/delete a QoS rule.
