35.3.2.1 Outgoing Authentication Protocol
Generally speaking, you should employ the strongest authentication protocol possible, for
obvious reasons. However, some vendor’s implementation includes a specific authentication
protocol in the user profile. It will disconnect if the negotiated protocol is different from that in
the user profile, even when the negotiated protocol is stronger than specified. If you encounter
a case where the peer disconnects right after a successful authentication, please make sure that
you specify the correct authentication protocol when connecting to such an implementation.
35.3.2.2 Nailed-Up Connection
A nailed-up connection is a dial-up line where the connection is always up regardless of traffic
demand. The ZyWALL does two things when you specify a nailed-up connection. The first is
that idle timeout is disabled. The second is that the ZyWALL will try to bring up the
connection when turned on and whenever the connection is down. A nailed-up connection can
be very expensive for obvious reasons.
Do not specify a nailed-up connection unless your telephone company offers flat-rate service
or you need a constant connection and the cost is of no concern.
The following table describes the fields not already described in
.
35.3.2.3 Metric
See

35.3.3 PPTP Encapsulation
If you change the Encapsulation to PPTP in menu 11.1, then you will see the next screen.
Table 213 Fields in Menu 11.1 (PPPoE Encapsulation Specific)
FIELD
DESCRIPTION
Service Name
If you are using PPPoE encapsulation, then type the name of your PPPoE service
here. Only valid with PPPoE encapsulation.
Authen
This field sets the authentication protocol used for outgoing calls.
Options for this field are:
CHAP/PAP - Your ZyWALL will accept either CHAP or PAP when requested by this
remote node.
CHAP - accept CHAP only.
PAP - accept PAP only.
Telco Option
Allocated
Budget
The field sets a ceiling for outgoing call time for this remote node. The default for this
field is 0 meaning no budget control.
Period(hr)
This field is the time period that the budget should be reset. For example, if we are
allowed to call this remote node for a maximum of 10 minutes every hour, then the
Allocated Budget is (10 minutes) and the Period(hr) is 1 (hour).
Schedules
You can apply up to four schedule sets here. For more details please refer to
Nailed-Up
Connection
This field specifies if you want to make the connection to this remote node a nailed-
up connection. More details are given earlier in this section.
Session
Options
Idle Timeout
Type the length of idle time (when there is no traffic from the ZyWALL to the remote
node) in seconds that can elapse before the ZyWALL automatically disconnects the
PPPoE connection. This option only applies when the ZyWALL initiates the call.
