Configuring the WAN
24 MM701G User Manual
3 Configure the following parameters for each session you set up as shown in the following
table:
Parameter Description
Session Name Enter a unique, descriptive identifier for the session. This name can have a maximum
of 15 characters with no spaces.
Protocol Select the message format to be used between the MM701G and the service
provider. You can configure each session with any of the three protocols listed
below.
• Select RFC 1483-Bridge if the MM701G forwards packets based on MAC
addresses. You can enable Spanning Tree when you select Bridge sessions. See
“Set Spanning Tree” on page 19 .
• Select RFC 1483-Router if the MM701G routes packets based on IP addresses.
• Select PPPoA if the MM701G establishes PPP sessions with the service provider.
If you select RFC 1483 Bridge or RFC 1483 Router protocol, you only need to set up
one session.
You can, however, configure a combination of RFC 1483 Router/Bridge and PPP
protocols for a multiple session configuration.
State Select Enable to activate this session. Select Disable to deactivate this session. You
can set the state for each session. You can also change the state for a session at any
time using this parameter.
IP Address Determine how an IP address is assigned to a session:
• If you selected PPPoA protocol, Dynamic is automatically selected. The service
provider automatically assigns an IP address to this session. The IP address
displays in the box.
• If you selected RFC 1483-Router protocol, you enter the IP address supplied by
the service provider in the box. Do not select Dynamic.
•
If you selected RFC 1483-Bridge protocol, you do not enter an IP address and
you do not select Dynamic.
Subnet Mask Determine how the subnet mask is assigned to a session:
• If you selected PPPoA protocol, the service provider automatically assigns a
Subnet Mask. The Subnet Mask displays in the box.
•
If you selected RFC 1483-Router protocol, you enter the Subnet Mask supplied
by the service provider in the box.
• If you selected RFC 1483-Bridge protocol, you do not enter a Subnet Mask.
NAT Enable or Disable the use of Network Address Translation (NAT) protocol to
translate private IP addresses (addresses on your LAN) to public IP addresses
assigned to each session (see IP Address above in this table for session IP
addresses).
