~Begin Chastise~ He posted to the SECURITY-BASICS mailing list. That would pretty much "determine the correct level of help" in my mind. ~End Chastise~ ~ ~Begin pathetic attempt at help~ And, technically speaking, "access-list 101 deny ip source ip destination ip" is the correct syntax, but the information he didn't get was: There is an implicit "deny any any" in all Cisco ACLs, which means a 1 line ACL to block one host would effectively block all hosts. & ACL built, but it still needs bound
From interface config mode,
"ip access-group 101 in interface " is the second part of the equation. & If there are no ACLs now, make it a two liner, the deny line, and: access-list 101 permit ip any any ~End pathetic attempt at help~ My .02 -----Original Message----- From: richardw [mailto:richardw () area52 allserve net] Sent: Monday, November 29, 2004 11:11 PM To: GuidoZ Cc: Carlos Garcia; Agarwal, Ankur; security-basics () securityfocus com Subject: Re: deny access Everyone, I want to take this opportunity to apologize for Guido. Carlos, if you still need help, email me off the list, and we'll help get squared away. Saludos, Richard GuidoZ wrote:
This is why I said it was better for him to find the answers on his own, and not just tell him the ACL format. Otherwise it's very likely that something will get messed up and he won't be able to fix it, or ask questions online. ;) Think about things before you act everyone. There is certainly nothing wrong with helping out someone in need, although, you must determine the correct level of help. -- Peace. ~G On Thu, 25 Nov 2004 19:40:40 -0700, Carlos Garcia <carlosg () cabonet net mx> wrote:ok i just write access-list 101 deny ip host 216.212.33.185 any is this ok? i put too access-list 101 deny ip 216.212.33.185 255.255.255.255 any... and can somebody tell me how to improve this, i run some servers and i
