Problem:

How can I connect to a SilkMeter License server via NAT (Network address translation)?

Resolution:

ANSWER
----------------------------------
To be able to connect to the license server via NAT it is necessary to make the license server hostname known to the naming system on the client machine. The most primitive naming system on Windows NT machines is the host list in the file:

\system32\drivers\etc\Hosts

Simply add an entry for the SilkMeter licenser server machine e.g.

123.123.123.123 pluto.mycompany.com


BACKGROUND
----------------------------------
Network Address Translation allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network. This means that only a single, unique IP address is required to represent an entire group of computers.

Basically the IP address of the SP machine will be presented to the NAT device and this will connect to the network the license Server is on using its own IP Address. i.e. the address it translated e.g.


SilkPerformer------------>NAT----------------->SilkMeter Server
(x.x.x.54)-------->(x.y.z.124)------------>(a.b.c.123)
(x.x.x.54)<><>


The same happens on the way back, the License Server is only able to see the NAT - it cannot see beyond this. The License Server will not be able to communicate directly with the SilkPerformer machine and this will cause the connection to fail.
