Security policy: exception question

L2 Linker

Hi, I'm trying to create a security policy that would block all critical traffic from source zone "A", to destination zone "B". However, I want to allow traffic from a specific IP in zone "A". How can I make an exception to allow that IP? I assume I could create a policy to allow that IP and then one below it block traffic from that zone but I would prefer not to do that- feel like it could be error prone, etc.


Thank you!

Hmm, define 'critical traffic'. Applications with high risk? Critical events from some security profile?


Sorry, should have elaborated on that part. By critical traffic I meant critical threats. Planning on doing that in the profiles.

I would suggest blocking at least critical events on all traffic, but ok.


Yeah, you have to make a rule for that specific IP first with security profile set to alert (or no security profile).

After that rule you make a rule from zone A to B with blocking security profile.

for a single or a few threats you can add an IP exception in the vulnerability protection profile in the exceptions tab, but if you want to exclude an ip from all scanning it's better to create a new rule with a different (alert all) profile

Ohh, didn't know about 'ip exemptions' query so far.

bonus: you can also add IP exceptions (or policy exceptions) directly from the threat log:

We do block all critical events already, just trying to get a better idea of some things and using a policy for it. I appreciate the help. I think my only option is creating two separate rules.

Hi TLineberry,


Use the 'Negate' option.


Create a rule which allows the traffic rule like this:

Source Zone = A

Source address = the ones you want to allow AND check the box for 'Negate'

Destination Zone = B

Destination Zone = Allow

Application/Service/Security profile = your choice

Action = Allow


The unwanted IPs would hit the interzone rule, IFF they don't happen to match some other rule.


Hope that helps.
