Endpoint 10.7 Firewall and ICMP

I've noticed that the default rule within the firewall allows ICMP.

Is it possible to create a rule that allows ICMP outbound on the workstation and the reply back in (good for diagnostics) but blocks any ICMP request coming in?

Thanks

Hi @TWBC 

Thank you for reaching out to community.

Default rules ICMP traffic via core networking. 

Disabling core networking is alternate option where this damages the network abruptly.

Please find the details below.

But for testing few pilot machines, you can disable to core networking rule and Duplicate the core networking rule as shown in the screenshot. 

In the new one, you test and see how this goes.

Hi Yaz,

 

Thanks for replying. I don't want to disable any of the core networking default rules.

ICMP appears under admin defined rather than core networking on my screen shot.

Is there no option to fine tune the ICMP setting - its either blocked or allowed for all icmp?

Many thanks

Hi @TWBC 

Kindly use the edit option for ICMP and see if you can change settings accordingly.

Kindly let us know how this goes.
