Hi All,
How/where do I configure an access-list to secure an ADSL interface that is configured for dynamic IP? Basically I just wanted to add only one or two lines to the ACL e.g.
access-list 102 permit tcp any host (dialer0 interface) established
access-list 102 deny ip any any log
inter dialer0
ip access-gr 102 in
If this can't be done then how does one secure a dialer interface that is configure for dynamic IP?
tks,
Donavan

Hi,
that should work, but it isn't the most secure solution. You might want to check out the Cisco IOS integrated firewall:

(Commands might be different for your device...search for the software configuration guide for your model)
