When DHCP is enabled, the RA 6300 acts as a DHCP client-by-proxy,
requesting a remote PPP client address first from the DHCP server
specified by the pref_dhcp1_addr parameter, then, if that server does
not respond, from the DHCP server specified by the pref_dhcp2_addr
parameter. For more information on DHCP, see Dynamic Allocation of
Network Addresses on page A-274.
About Addressing Via the acp_dialup File
Addressing using the acp_dialup file offers the ability to assign IP
addresses to individual users. When the address_origin parameter is set
to acp, the RA 6300 uses the host-resident acp_dialup file to handle IP
addressing. The file resides in the RA 6300 install directory. For
information on making entries into the acp_dialup file, see Creating the
acp_dialup File on page A-276.
Any ACP address request that comes from the RA 6300 includes the
RA 6300 address and an associated user name, which are used as keys in
this file. Once the keys are matched, the corresponding user addresses
are returned to the caller on the RA 6300.
As mentioned earlier, you can also use the acp_dialup file to
enable dynamic IP addressing for individual users, by setting
the remote address field of the file to dhcp. For complete
information, see Dynamic Allocation of Network Addresses
on page A-274
About Addressing Using Asynchronous Port Parameters
Setting the address_origin parameter to local causes IP addressing for
the RA 6300 to be controlled by the values of two asynchronous port
parameters, local_address and remote_address. This method of fixed
IP addressing associates IP addresses with specific ports. For complete
information on the use of the local_address and remote_address
parameters, refer to Determining Dial-up Addresses using the acp_dialup
File on page A-278.
