Chapter 3 Configuring PPP over Ethernet with NAT
Configure the Dialer Interface
Step 7
dialer-group group-number
Example:
Router(config-if)# dialer group 1
Router(config-if)#
Assigns the dialer interface to a dialer group
(1–10).
Tip Using a dialer group controls access to
your router.
Step 8
exit
Example:
Router(config-if)# exit
Router(config)#
Exits the dialer 0 interface configuration.
Step 9
dialer-list dialer-group protocol protocol-name
{permit | deny | list access-list-number |
access-group}
Example:
Router(config)# dialer-list 1 protocol ip
permit
Router(config)#
Creates a dialer list and associates a dial group
with it. Packets are then forwarded through the
specified interface dialer group.
For details about this command and additional
parameters that can be set, see the
Cisco IOS Dial
Technologies Command Reference.
Step 10
ip route prefix mask {interface-type
interface-number}
Example:
Router(config)# ip route 10.10.25.2
0.255.255.255 dialer 0
Router(config)#
Sets the IP route for the default gateway for the
dialer 0 interface.
For details about this command and additional
parameters that can be set, see the
Cisco IOS IP
Command Reference, Volume 2; Routing
Protocols.
