Prestige 128+ ISDN Router
L2TP 10-9
Peer Host Name This is the name of the peer computer at the far end.
Shared Secret This password must be the same for both endpoints.
IP Address A receiving L2TP endpoint must have a fixed, globally
unique IP address.
Proxy Mode
For the LNS in this case, choose Proxy for Tunneling Mode in menu 11.1 as
the LNS is asking the LAC to place a call on its behalf. If outgoing calls are
allowed and there is an idle phone line, the LAC will act as a proxy for the LNS.
The menu 10.1 entries are the same as described above.
Figure 10-7 Prestige in Proxy mode.
10.4.3 Prestige as LAC
Endpoint Name in Menu 10.1 is the key setting for the LAC for both incoming
and outgoing calls.
Incoming Call
For calls to a LAC, the long form of NAI (Network Access Identifier) is used.
The NAI is in the form of
username@realm, where realm is typically a
domain name, e.g., [e-mail]. The realm is the key in the search of the
endpoint. The LAC will search for the Endpoint Name in its endpoint table to
know whether to create a tunnel or not. If the realm matches the name of one of
the endpoints in the LAC, then the LAC handles this as a request for L2TP
