access-list 1 deny 192.168.1.1
access-list 1 permit any
Substitute 192.168.1.1 for the IP address you want to block. Dont forget the permit at the end or every IP addr will be denied.
Then you must apply the ACL to the interface you want, and specifiy which direction. In this case, if you have a serial interface #0/1 connected to the Internet, it would look like below:
interface Serial0/1
ip access-group 1 out

From: Robert Canary <[EMAIL PROTECTED]> Reply-To: [EMAIL PROTECTED] To: "[EMAIL PROTECTED] Redhat discusion list" <[EMAIL PROTECTED]> Subject: [OFFTOPIC] Blocking IP at a Cisco Date: Sun, 10 Nov 2002 20:52:02 -0600I'm really sorry for this far off post... I am trying to figure out how to block an internal IP address from going out on the internet. I just am not a Cisco person, and I am trying to learn it. Any help or pointers to some online docs would be great, I bought this router second handed so I have no Cisco support stuff. Thanks in advance :-) -- robert canary -- redhat-list mailing list unsubscribe mailto:redhat-list-request@;redhat.com?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
