Chapter 13 Configuring Dial Backup and Remote Management Configuring Dial Backup and Remote Management Through the Console or Auxiliary Port Step 10 Command Purpose ip nat inside source {list access-list-number} Enables dynamic translation of addresses on the {interface type number | pool name} [overload] inside interface. Example: Router(config)# ip nat inside source list 101 interface Dialer 3 overload Step 11 ip route prefix mask {ip-address | interface-type Sets the IP route to point to the dialer interface as interface-number [ip-address]} a default gateway. Example: Router(config)# ip route 0.0.0.0 0.0.0.0 22.0.0.2 Router(config)# Step 12 access-list access-list-number {deny | permit} Defines an extended access list that indicates source [source-wildcard] which addresses need translation. Example: Router(config)# access-list 1 permit 192.168.0.0 0.0.255.255 any Step 13 dialerwatch-list group-number {ip ip-address address-mask | delay route-check initial seconds} Evaluates the status of the primary link, based on the existence of routes to the peer. 22.0.0.2 is the peer IP address of the ISP. Example: Router(config)# dialer watch-list 1 ip 22.0.0.2 255.255.255.255 Router(config)# Step 14 line [aux | console | tty | vty] line-number [ending-line-number] Enters configuration mode for the line interface. Example: Router(config)# line console 0 Router(config-line)# Step 15 modem enable Example: Router(config-line)# modem enable Router(config-line)# Switches the port from console to auxiliary port function. Step 16 exit Enters global configuration mode. Example: Router(config-line)# exit Router(config)# 13-12 Cisco 850 Series and Cisco 870 Series Access Routers Software Configuration Guide OL-5332-01

Configuring Dial Backup and Remote Management
Configuring Dial Backup and Remote Management Through the Console or Auxiliary Port
Step 10
ip nat inside source
{
list
access-list-number
}
{
interface
type number |
pool
name
} [
overload
]
Example:
Router(config)#
ip nat inside source list
101
interface Dialer 3 overload
Enables dynamic translation of addresses on the
inside interface.
Step 11
ip route
prefix mask
{
ip-address
|
interface-type
interface-number
[
ip-address
]}
Example:
Router(config)#
ip route 0.0.0.0 0.0.0.0
22.0.0.2
Router(config)#
Sets the IP route to point to the dialer interface as
a default gateway.
Step 12
access-list
access-list-number
{
deny
|
permit
}
source
[
source-wildcard
]
Example:
Router(config)#
access-list 1
permit
192.168.0.0 0.0.255.255 any
Defines an extended access list that indicates
which addresses need translation.
Step 13
dialerwatch-list
group-number
{
ip
ip-address
address-mask
|
delay route-check initial
seconds
}
Example:
Router(config)#
dialer watch-list 1 ip
22.0.0.2 255.255.255.255
Router(config)#
Evaluates the status of the primary link, based on
the existence of routes to the peer. 22.0.0.2 is the
peer IP address of the ISP.
Step 14
line
[
aux
|
console
|
tty
|
vty
]
line-number
[
ending-line-number
]
Example:
Router(config)#
line console 0
Router(config-line)#
Enters configuration mode for the line interface.
Step 15
modem enable
Example:
Router(config-line)#
modem enable
Router(config-line)#
Switches the port from console to auxiliary port
function.
Step 16
exit
Example:
Router(config-line)#
exit
Router(config)#
Enters global configuration mode.
