    opening 443 should be enough as https uses port 443. I don’t know in details how paypal api works. is it possible that other ports are involved during the exchange your application – paypal api? try a tcpdump or watch the firewall log in order to see if there are packet exchanges on other ports and so are blocked by the firewall.
