General Tab Field Descriptions
Configure the following parameters:
IPv4 Local IP
Address
The IPV4 IP address of the IOLAN end of the PPP link. For routing to work,
you must enter a local IP address. Choose an address that is part of the same
network or subnetwork as the remote end; for example, if the remote end is
address 192.101.34.146, your local IP address can be 192.101.34.145. Do not
use the IOLAN’s (main) IP address in this field; if you do so, routing will not
take place correctly.
IPv4 Remote IP
Address
The IPV4 IP address of the remote end of the PPP link. Choose an address that
is part of the same network or subnetwork as the IOLAN. If you set the PPP
parameter IP Address Negotiation to On, the IOLAN will ignore the remote IP
address value you enter here and will allow the remote end to specify its IP
address. If your user is authenticated by RADIUS and the RADIUS parameter
Framed-Address is set in the RADIUS file, the IOLAN will use the value in
the RADIUS file in preference to the value configured here. The exception to
this rule is a
Framed-Address value in the RADIUS file of 255.255.255.254;
this value allows the IOLAN to use the remote IP address value configured
here.
IPv4 Subnet Mask The network subnet mask. For example, 255.255.0.0. If your user is
authenticated by RADIUS and the RADIUS parameter
Framed-Netmask is set
in the RADIUS file, the IOLAN will use the value in the RADIUS file in
preference to the value configured here.
Negotiate IP
Address
Automatically
Specifies whether or not IP address negotiation will take place. IP address
negotiation is where the IOLAN allows the remote end to specify its IP
address. When
On, the IP address specified by the remote end will be used in
preference to the
Remote IP Address set for a Serial Port. When Off, the
Remote IP Address set for the Serial Port will be used.
Default: Disabled
Dynamic DNS
Button
Launches the Dynamic DNS window when IP Address Negotiation is enabled,
which can then update the DNS server with the IP address that is negotiated
and accepted for the PPP session.
See Dynamic DNS Field Descriptions on page 186 for more information.
