We have just begun to use the SonicWall TZ190 series firewall and we would like to be able to redirect non-standard ports to the standard ports on specific private IP address with our network.
Example:
mstsc /console /v:123.123.123.123:4000
We would be using port 4000 to the public address and redirecting to a standard RDP 3389 on a private IP. This way we do not change the standard listening port on the network boxes.
