Are you sure that there isn't anything else in your rule-base cancelling this out? I have used it and it worked.
Do me a favour and move your block rule to the top of your rule-base and push the policy and try again. Any difference? -----Original Message----- From: theG man [mailto:[EMAIL PROTECTED] Sent: 11 May 2004 20:22 To: [EMAIL PROTECTED] Subject: Re: [FW-1] how to block MSN, AOL, Yahoo messenger with R54 or R55 Hi all, Just noticed, Yahoo messenger works too, On NG R54 or R55, there is a group called messenger service, which are AOL, Yahoo messenger,and MSN, I checked them all, aftter creating the rule like ANY ANY messenger services DROP,,,, AOL is not working, thats fine, but as I mentioned in my privouse email, MSN keeps working, and just noticed Yahoo messenger works too. The funny thing is Yahoo, or MSN traffic goes over Telnet, HTTP or any port which are not blocked (by that Messenger serivices group) I just read somewhere, You need to block by IP address of the servers, otherwise, these chat services find different port everytime to comunicate. anyone has a better Idea? theG man <[EMAIL PROTECTED]> wrote: Hi everyone, I know R54 and R55, has a group for Messenger services, like AOL, Yahoo, and MSN, after creating the rule and pushing policy, YAHOO and AOL not working but MSN still working, any idea? does anyone knows what servers (IP addresses) MSN messenger uses, so I can block them by IP addresses. FYI_Checkpoint knowledgebase IP addresses for MSN is not updated and is old. what would be the command for nslookup to get the server IP addresses for MSN messenger? thanks --------------------------------- Do you Yahoo!?
