Anti-virus Block Option Not Available

L3 Networker

Hello Community,

 

I would like to set an Antivirus action to 'Block', but for some reason that option isn't available, see image. However, it has been available on my other PA-VM. Can someone explain why I can't see that option here?

These are the only available actions for antivirus profiles.  Drop along with reset-both are the same as "block".  Drop will silently drop the traffic.  Reset-both will send TCP resets to both the client and server (or drops the traffic if its UDP).

 

I have my profiles configured to reset-both.  In the case of a incoming virus over SMTP, reset-both will send a 541 response to the mail server preventing it from attempting to resend the blocked message again.

 

You can find more information about this in the administrator's guide.

Has this been changed in recent versions? We are running 6.1.10 and have the block option in our antivirus profile.

Hi,

 

This is mentioned in the 7.0 release notes.

It's one of the changes to default behavior in PAN-OS 7.0 :

 

 

---Release Notes---

The default actions for handling threats now are alert or reset-both (sides of the connection). In releases prior to PAN-OS 7.0.0, the defaults were alert or block. On upgrade, the block action will be converted to reset-both; and the drop-packets option is now renamed as drop. On downgrade, all actions configured as drop or reset, will be converted to block.

---Release Notes---

 

regards,

-Kim.

Block in older version is reset-both in newer version. Plus there are now options to drop silently or reset only one side.
