Step 2 Create the dial-out/fax-out modem pool for the 40 local employees connected to the headquarters LAN.
This modem pool contains 12 fax-capable MICA modems. No DNIS is assigned to the pool. Because
lines 85 to 96 are used for the dial-out and fax-out modem services, the asynchronous lines are
configured for reverse Telnet. This configuration is needed for the Telnet extensions to work with the
dial-out application, which is installed on the LAN PCs.
Router(config)# modem-pool dialoutfolks
Router(config-modem-pool)# pool-range 85-96
Router(config-modem-pool)# exit
Router(config)# line 85-96
Router(config-line)# refuse-message z [!NMM!] No Modems Available z
Router(config-line)# exec-timeout 0 0
Router(config-line)# autoselect during-login
Router(config-line)# autoselect ppp
Router(config-line)# modem inout
Router(config-line)# rotary 1
Router(config-line)# transport preferred telnet
Router(config-line)# transport input all
Router(config-line)# exit
Router(config)#
Step 3 Configure the group asynchronous interface, which assigns core protocol characteristics to all the
asynchronous interfaces in the system. Regardless of the direction that the modems are dialing, all
modems in the access server leverage this group asynchronous configuration.
Router(config)# interface group-async 1
Router(config-if)# ip unnumbered ethernet 0
Router(config-if)# encapsulation ppp
Router(config-if)# async mode interactive
Router(config-if)# ppp authentication chap pap paplocal
Router(config-if)# peer default ip address pool bidir_dial_pool
Router(config-if)# no cdp enable
Router(config-if)# no ip mroute cache
Router(config-if)# no ip route cache
Router(config-if)# async dynamic routing
Router(config-if)# async dynamic address
Router(config-if)# group range 1-96
Building configuration...
Router(config-if)# exit
Step 4 Create an IP address pool for all the dial-in clients and dial-out clients. Both types of clients borrow
addresses from this shared pool.
Router(config)# ip local pool bidir_dial_pool 10.4.1.1 10.4.1.96
Router(config)# ^z
Router# copy running-config startup-config
Step 5 (Optional) If you are using CiscoSecure AAA and a remote TACACS server, include the following
security statements on the access server:
Router(config)# aaa new-model
Router(config)# aaa authentication login default tacacs+
Router(config)# aaa authentication login noaaa local
Router(config)# aaa authentication login logintac tacacs+
Router(config)# aaa authentication ppp ppptac tacacs+
Router(config)# aaa authentication ppp paplocal local
Router(config)# aaa authorization exec tacacs+
Router(config)# aaa authorization network tacacs+
Router(config)# aaa authorization reverse-access tacacs+
Router(config)# aaa accounting exec start-stop tacacs+
Router(config)# aaa accounting network start-stop tacacs+
Router(config)# aaa accounting update newinfo
Router(config)# enable password cisco
