Allow traffic after "decrypt-error"?

Maxstr — Fri, 21 Jun 2019 15:04:33 GMT

Is there any way to allow traffic after "decrypt-error"? I get a lot of decrypt-errors showing up in the logs when SSL decryption is enabled. Most of it is from amazonaws.com (even though I excluded it from decryption). I would rather just allow the traffic to pass, but instead it's getting denied by default, and I can't find any way to allow it instead.

I'm running 8.1.5

You can do the SSL decrypt exempt for particular website or destination address under the policies and decryption

Under device

ssl decrypt exclusion you can add the particular website there which gived decrypt error.

Then your traffic to that website will not be decrypted.

Hi @Maxstr

Depending on the actual reason you can allow specific connection (with a decryption profile), even if users then need to make a second attempt as the firewall needs the first try to add the website to an exclusion table. But there are situations (somehow bugs) where this probably isn't possible. So first I would update to 8.1.8 (=preferred release from Paloalto: https://live.paloaltonetworks.com/t5/Customer-Resources/Support-PAN-OS-Software-Release-Guidance/ta-p/258304 ). If the problem then is still there you could either open a support case or use the solution proposed by @MP18 and manually exclude the websites that generate errors - at least if you need to access these websites.
