Address assignment buttons control the source of the address assignment.

•

Security server

 - RAC searches the acp_dialup file for the user

name of the remote client and sets the remote address and other
related values.

•

If the file contains a matching user name and remote address
in the

acp_dialup

 file, the RAC uses that value.

•

If the file does not contain a matching user name, the RAC
uses the local value - the value from the RAC.

•

If the remote address is set to 0.0.0.0 the RAC negotiates
for the address with the remote PPP client. The connection
is denied for a remote SLIP client.

•

dchp

 - the RAC contacts DHCP server to request the PPP dialup

addresses.

•

Local

 - the RAC uses the values from the

Remote Address

 and

Subnet

 fields.

The

Remote Address

 box allows you to assign consecutive remote addresses

to RAC ports or B-channels for SLIP or PPP connections.You can set up
remote addressing from the

PPP Dial Access

window only for these devices:

5393/6300, 5399, and 8000. For other devices use the

Remote Addressing

window. This window is described on page 4-43.

The

Remote Address

 window uses the

First Remote Address

and

 Subnet Mask

fields to enter and display information. The

Last Remote Address

field

displays the last remote address; you cannot enter text here.

•

First Remote Address

assigns the first IP address of the entire

range of ports or channels for the selected Annex. If this field
displays

0.0.0.0,

all addresses in the range of ports or channels

are 0.0.0.0
