DDRwithAccessLists

Here is an example of how you define the dialer list to use an access list:

804A(config)#dialer-list 1 list 110

804A(config)#access-list 110 permit tcp any any eq smtp

804A(config)#access-list 110 permit tcp any any eq telnet

804A(config)#int bri0

804A(config-if)#dialer-group 1
