Hi,
is it possible to nat a rang of ports with NetNatStaticMapping?

Add-NetNatStaticMapping -ExternalIPAddress "0.0.0.0/24" -ExternalPort 5000-51000 -Protocol TCP -InternalIPAddress "10.0.20.15" -InternalPort 5000-51000 -NatName NATNetwork

if not, any idea how to do this?

    Hi,
    Technically it is not possible to map multiple ports on a NAT policy. The best method of accomplishing your requirement is to configure multiple NAT policies mapping single source and destination ports if the number of ports is not large.

    Thanks for your time!

    This would means that I have to map 1000 ports manually!!

    Hi,
    It's a pity that there seems to be no command to map ports at the same time so far.
    Since ports need to be mapped one by one, mapping 1000 ports manually is indeed a big project.

    Not tested, but something along the lines of:

    50000..51000 | % {Add-NetNatStaticMapping -ExternalIPAddress "0.0.0.0/24" -ExternalPort $_ -Protocol TCP -InternalIPAddress "10.0.20.15" -InternalPort $_ -NatName NATNetwork }
