Looking to mirror traffic from our global protect VPN to a mirror port

Ravens1 — Mon, 15 Jun 2020 19:40:34 GMT

We are looking to send traffic to a mirror port similar to the decrypt and mirror functionality for our global protect VPN. We essentially would like to mirror all traffic coming and going to clients connected to our global protect VPN traffic to an external appliance, In order to be useful it needs to show the IP assigned to the client. We have looked a mirroring the external segment to another port or doing the same on the network but only shows the tunneling traffic.

Hi Ravens1,

Do you want to decrypt the user traffic (e.g. HTTPS) tunneled via GP IPSec/SSL VPN tunnel?
If so, the tunneled-traffic (e.g. HTTPS, Source IP will be the GP-assigned IP address) could hit an SSL Decryption Policy, if configured, & it can be forwarded to Decryption Mirroring port (just like other decrypted traffic forwarded to the Decrypt Mirror port).

General document for Decryption Port Mirroring: https://docs.paloaltonetworks.com/pan-os/8-1/pan-os-admin/decryption/configure-decryption-port-mirroring
