Hello Matt, It looks good to me. Since, traffic traversing through PAN firewall twice, we may need to perform a source NAT for this traffic at HQ core switch. A source NAT with ensuring the symmetric return of the traffic through the HQ core switch. As per my understanding, your traffic is flowing like above mentioned diagram. The green line is for return traffic from internet. So, only a source NAT in your HQ core switch can ensure the return traffic to go back to HQ core through content filter. Otherwise, if you perform NAT on PAN firewall, return traffic will not travese through HQ core and content filter, since PAN firewall will identify the direct route to reach remote user's subnet through VPN tunnel. Hope this helps. Thanks
