Using RGS through a firewall
The RGS Receiver can use the public IP address of the remote computer so that RGS can be used
through a simple firewall. To take advantage of this feature, the remote and local computer firewalls
must both support Network Address Translation (NAT). In addition, the remote computer firewall must
support port forwarding.
NOTE: For more information on how to set up port forwarding on your firewall, see the
documentation for your firewall.
The port used by the RGS Receiver is assigned by the operating system of the local computer and
can vary.
The RGS Sender listens on port 42966 by default, but the port number can be changed using the
Rgsender.Network.Port property as described in
RGS properties on page 76. If this property is
used to change the port number from its default value of 42966, the port number must then be
specified when establishing an RGS connection. Either of the following formats are accepted:
<hostname>:<port>
<IPaddress>:<port>
Remote computer power saving states
In order for a local computer to establish connection to a remote computer, the remote computer
cannot be in a power saving state, such as Windows hibernate or standby. Furthermore, the remote
computer cannot utilize wake-on-LAN in an attempt to power-up in order to respond to a connection
request from the local computer—the remote computer must be powered-up, and able to respond to
an RGS connection request at all times.
