3.8 Nailed-Up Connection (PPP)
A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand. The
Prestige does two things when you specify a nailed-up connection. The first is that idle timeout is disabled.
The second is that the Prestige 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
3.9 NAT
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a
packet, for example, the source address of an outgoing packet, used within one network to a different IP
address known within another network.
