4-4 Using RGS through a firewall New at RGS 5.1.5 is the ability for the Receiver to use the public IP address of the Sender. This feature has been added to allow RGS to be used through a firewall. To take advantage of this feature, the Sender and Receiver firewalls must both support NAT (Network Address Translation). In addition, the Sender firewall must support port forwarding (see Figure 4-7). Figure 4-7 RGS operation through a firewall NAT source IP: port dest IP: port 192.168.0.10 : 42966 192.168.0.1 : 678 192.168.0.10 : 42966 Firewall Sender 192.168.0.1 NAT-enabled router source IP: port 15.2.A.B : 543 dest IP: port 15.2.C.D:678 15.2.A.B Public IP addresses Internet 15.2.C.D Firewalls can change the source port numbers (examples shown) source IP: port 192.168.0.1 : 543 Firewall dest IP: port 192.168.0.5 : 3279 This port number can vary. 192.168.0. 5 : 3279 NAT-enabled router 192.168.0.1 Receiver source IP: port 192.168.0.1 : 678 dest IP: port 192.168.0.10 : 42966 source IP: port 15.2.C.D : 678 dest IP: port 15.2.A.B : 42966 source IP: port 192.168.0.5 : 3279 dest IP: port 15.2.A.B : 42966 Port Forwarding NAT New at RGS 5.1.5 is the ability for the Receiver to use the public IP address of the Sender NOTE: The port used by the RGS Receiver is assigned by the Local Computer OS and can vary. The RGS Sender listens on TCP/IP port 42966. At RGS 5.2.5, the capability was added to specify the port number used by the RGS Sender. The default Sender port number is 42966, as noted above. The Sender port number can be changed using the Rgsender.Network.Port property, as described on page 158. If this property is used to change the Sender port number from its default value of 42966, the Sender port number must then be specified in establishing an RGS connection from the Receiver to the Sender.
