4.1.2 PPPoE Encapsulation
The ZyWALL supports PPPoE (Point-to-Point Protocol over Ethernet). You can only use PPPoE
encapsulation when you’re using the ZyWALL with an xDSL modem as the WAN device. If you change
the
Encapsulation to PPPoE, then you will see the next screen. Please see the Appendices for more
information on PPPoE.

Outgoing Authentication Protocol
Generally speaking, you should employ the strongest authentication protocol possible, for obvious reasons.
However, some vendor’s implementation includes 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 the 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.
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
Table 4-1 already.
