NAT (Network Address Translation) Firewalls

If the computer containing Optimod-PC is on a network behind a NAT firewall, you
must configure the firewall to allow outside access to the Optimod-PC computer
from another computer outside the firewall. This is usually done via router port for-
warding: The Optimod-PC port(s) are forwarded to the Optimod-PC computer by
configuring the NAT firewall accordingly. The Optimod-PC computer is then ad-
dressed with the network IP address (WAN) instead of the actual IP address of the
Optimod-PC computer.
For a single IP addressable network, each port can only be used once. Therefore, if
you have more than one computer with Optimod-PC requiring outside access, each
computer must have a unique OPTIMOD-PC port.
Refer to your router/firewall documentation for the exact configuration procedure,
paying close attention to the network security risks inherent in configuration
changes.
