Floating license to use at a distant location

Hi,

We are using a floating license hosted on a local server (under Debian) and we do a simple 'port at server' to access it, but we sometimes need to use it at one of our customer place when running tests.

So my question is how to be able to do so ? I am new to this things and I couldn't find tutorials, so if any exists I would really appreciate if someone can point them out.

Thank you and sorry for my poor english.
