the layer can pass onwards. This value is 1492 for PPPoE.
ENABLE PPP Manual MODE
Use this button to manually connect/disconnect PPP sessions.
ENABLE PPP DEBUG MODE
When this option is selected, the system will put more PPP connection information
into the system log. This is for debugging errors and not for normal usage.
BRIDGE PPPOE FRAMES BETWEEN WAN AND LOCAL PORTS
(This option is hidden when PPP IP Extension is enabled)
When Enabled, this creates local PPPoE connections to the WAN side. Enable this
option only if all LAN-side devices are running PPPoE clients, otherwise disable it.
The VI-3223u supports pass-through PPPoE sessions from the LAN side while
simultaneously running a PPPoE client from non-PPPoE LAN devices.

multicast. This protocol is used by IPv4 hosts to report their multicast group
memberships to any neighboring multicast routers.
STEP 3: Choose an interface to be the default gateway.
Click Next to continue or click Back to return to the previous step.
STEP 4:
Select DNS Server Interface from available WAN interfaces OR enter static DNS
server IP addresses for the system. In ATM mode, if only a single PVC with IPoA or
static IPoE protocol is configured, Static DNS server IP addresses must be entered.
