Outbound SSL Decryption Capabilities

I know outbound SSL decryption can work when a client inside the network is accessing a secure website on the internet.  But can SSL decryption work when a client on the internal network attempts to make a vpn connection to a vpn server using an SSL VPN connection elsewhere on the public internet?  Can SSL decryption intercept that connection and read the contents of the vpn session?  Thanks!

Hi

 

Yes this will work if the vpn session falls under these conditions:

 

- the ssl tunnel must be based on TLS (regular ssl), no ipsec is used

- a client certificate is not required as the firewall is not able to inject a client certificate

OK thanks - if both firewalls (the one doing the outbound SSL decryption) and the one on the internet (running the VPN server) were both Palo Alto's - could the one on the internet be configured to require a client certificate, and so prevent outbound SSL decryption from working?
