Description
The amount of time before the PPP
connection drops if there is no activity. A
value of 0 means stay connected even if
your network stays idle.
The type of authentication protocol used
during the negotiation of the PPP
connection. This protocol may be specified
by your ISP. One option, CHAP (Challenge
Handshake Authentication Protocol),
encrypts your user name and password
during the negotiation. Password
Authentication Protocol does not.
Network Address Translation. By default,
this setting is Enabled. NAT keeps a table
of individual private IP addresses in your
network and refers to the table when
incoming requests are made. If no matches
are found, the incoming data cannot come
into your network. An Enabled setting
keeps your IP addresses hidden from
outside users. Disabled is some times
used if you want to use Public IP
addresses.
Maximum Transmission Unit. Largest
physical packet size, measured in bytes,
that the modem can send. Any messages
larger than the MTU have to be fragmented
before being sent.
Enable this button if your service provider
is using DHCP and you are using the 1483
protocol. If you are unsure of what your
service provider is using select this button.
Enable this button if you are using a static
IP address and you are using 1483
protocol. Typically you have to request and
pay extra for a static IP address.
