Local Traffic, SSL Profile with Client Cert "Require" doesn't work for VPN under Mac OS

Hi,

 

I've defined the SSL Client Profile with "Require" at Client Certificate section to add some extra security and avoid that you can reach the logon page without a valid Certificate.

 

However, now the Network Access VPN doesn't work anymore under Mac OS. Under Windows with F5VPN Helper Application or F5 Edge Client, I'm requested to select the certificate and the VPN establishes successfully. Under Mac OS it doesn't ask me to select a certificate...

 

If I change to "Request" the VPN under Mac OS works, but this defy the scope of why I want to use "Require" as explained above.

 

Worth to mention that login via browser works with both Windows and Mac OS, but VPN only with Windows.

 

The BIG-IP version is 13.0.0 if this helps. I had the same with 12.x

 

Any ideas?

 

Thanks!
