Explanation of non-typical and interesting parameters:
Destination port (from) and Destination port (to)
DNAT rule applies to UDP data with destination ports within the 20001-20015 range only
Input interface
Data must be received on any ETH port
Range mapping
Set to “Port to IP address” - i.e., destination ports change the destination IP address(es) ac-
cordingly.
Rewrite destination IP and Rewrite destination port
Set to IP 10.10.10.1 and port 502 - resulting in a range of IPs 10.10.10.1 - 10.10.10.15 due
to Destination ports of received UDP data in a range of 20001-20015 (15 ports = 15 IP ad-
dresses). A new port is always 20000 (i.e., DNP3 default port).
Rewrite destination IP
IP address, default = 0.0.0.0/0
Defines a new destination address. Value 0.0.0.0/0 means, that the destination address is not
changed.
Rewrite destination port
Number {0 – 65535}, default = 0
Defines a new destination port (rewriting multiple defined ports into one). Value 0 means, that the
destination port is not changed.
