To resolve this problem, you must configure the plugin to use an external IP address. If externalIPAddress
is configured as 10.1.1.1 for this desktop, the plugin gives the client an IP address of 10.1.1.1 when making
desktop protocol connections to the desktop. For PCoIP, the PCoIP Secure Gateway service must be started
on the desktop for this setup.
For port mapping, when the desktop uses the standard PCoIP port 4172, but the client must use a different
destination port, mapped to port 4172 at the port mapping device, you must configure the plugin for this
setup. If the port mapping device maps port 14172 to 4172, the client must use a destination port of 14172 for
PCoIP. You must configure this setup for PCoIP. Set externalPCoIPPortin the plugin to 14172.
In a configuration which uses NAT and port mapping, and the externalIPAdress is set to 10.1.1.1, which is
network translated to 192.168.1.1, and externalPColPPort is set to 14172, which is port mapped to 4172.

As with the external PCoIP TCP/UDP port configuration for PCoIP, if the RDP port (3389) or the Framework
Channel port (32111) is port mapped, you must configure externalRDPPort and
externalFrameworkChannelPort to specify the TCP port numbers that the client will use to make these
connections through a port mapping device.
