L3 Networker

For a while ive seen a good amount of unknown-tcp connections out to yahoo.com domains.

Anyone else seeing this?

Please make sure the security policy allows all the yahoo applications as stated in applipedia or at least the ones which you are trying to access (for e.g. yahoo-mail, yahoo-finance-posting) or you have a application-any service-any policy configured.

Please refer to this blog: unknown-tcp / udp - please explain

Is there any specific yahoo-based application is not identified by the PAN FW. I saw a similar issue for SMTP.yahoo.com for port 465 which is not mentioned on the Applipedia ( Application Research Center )


Could you please explain the issue in details, so it would be easier for us to provide you the exact answer.
