5. To configure the connection sharing type, select Disable, Enable or VLAN from the Sharing
drop down.
Configure connection sharing as directed by your ISP.
DSL creates a permanent virtual connection (PVC) between network endpoints. This
connection may be shared where each device may have access to the packets, or the
connection may be segregated. In other words multiple connections over the same PVC are
supported. VLAN support requires that the ISP have VLANs supported and identified
Disable

VLAN
Sets up a virtual LAN. To configure the VLAN you will need to provide a VLAN ID

Idle Timeout
Specifies that PPPoE connection should disconnect if the link has no activity
detected for the specified number of seconds. This field is used in conjunction with
the On Demand feature and is enabled only when the On Demand field is
checked. To disable the timeout feature, enter a zero in this field.
Authentication
Specifies the authentication protocol:
• Auto (the protocol is selected by the Central Office modem)
• PAP (Password Authentication Protocol)
• CHAP (Challenge Handshake Authentication Protocol).
Microsoft CHAP v2 is also supported with the Auto and CHAP options. However,
MS CHAP v1 is not supported.

to wait without being connected to your provider before terminating the connection.
To ensure that the link is always active, enter a 0 in this field. You can also enter
any positive integer value in this field.
MTU
The Maximum Transmission Unit the DSL connection can send. It is a negotiated
value. The PPPoE interface default MTU is 1492 (max) and PPPoA default MTU is
1500 (max). The minimum MTU value is 64.

Gateway
If checked, this WAN connection acts as the default gateway to the Internet.
Enforce MTU
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 MTU by
changing TCP Maximum Segment Size to the PPP MTU.
The Enforce MTU feature is enabled by default. It forces all TCP traffic to conform
with PPP MTU by changing TCP maximum segment size to PPP MTU. If it is
disabled, you may have issues accessing some Internet sites.
