Palo Alto Global Protect

[ITSMC24]

Hello. 

   I am looking to setup and use Palo Alto's Global Protect feature; The question I have is if I have only 1 egress port (WAN) port that is public-facing, can I setup my Global Protect on that egress port or do I need to use another port for egress and assign that port to both gateway and portal? Or can I use my one (egress) port to be a gateway and portal, while leading internal clients to the internet? 

Thanks.
