Prestige 662HW Series User’s Guide
Wizard Setup 3-5
Regardless of your particular situation, do not create an
arbitrary IP address; always follow the guidelines above. For more
information on address assignment, please refer to RFC 1597,
Address Allocation for Private Internets and RFC 1466, Guidelines
for Management of IP Address Space.
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.
