SSL Forward Proxy Problems

L0 Member


I'm seeking some guidance from those who have configured this, and have it working.

I'm trying to configure the SSL forward proxy feature, to decrypt web traffic.

I can get this working no problems using a self signed certificate, but this is problematic for devices such as phones and tablets.  I can certainly push the certificate to computers using group policy, but need to support visiting people with BYODs and also portable devices.

I have purchased a certificate, from a public CA.

However, when installing said certificate on the firewall, it sees it as "trusted" and says it's ok, but the option to use it as the forward trust certificate is greyed out.
I've had a tac case and even tac don't seem to know why.

They have suggested I make a combined certificate which includes the intermediate certificates from the CA, which I have done, and it made no difference.

TAC can't seem to work out how to make this feature work, and neither can I.
Is there anyone using a public CA signed certificate for this purpose? How did you make it work?
TAC have assured me that the version of PanOS I am using does not have a bug, and it should just work.

Please help.  Thankyou in advance.

For SSL decrypt/encrypt you need a CA (certificate authority), a certificate does not suffice.

With this CA the firewall signs a new certificate which has almost all parameters copied from the "original" web site certificate.
