It tries to use UDP 4501.

Client will show protocol as IPSec.

If client is in limited network then GlobalProtect will fall back to TCP 443.

Client will show protocol SSL.

Issue is that in case on SSL TCP packets received from application are encapsulated into second TCP packet.

It adds overhead and can cause problems in case of bad connectivity (Search what "TCP meltdown" means).
