You should probably install SAPRouter (see http://service.sap.com/saprouter). It redirects incoming SAPGUI connections to the correct SAP systems. It has many connection and security configuration settings (see the online documentation for more information). SAPRouter listens by default to port 3299. You will have to open this port on your firewall.
