For a quite specific need i am looking if it is possible for a client
connecting to the router from the outside to indentify his himself to
the router which then would then create a rule opening a new port then
translating this port toward a  machine in the LAN 192.168.1.Y port  Z.
Z is fixed Y depends on the user .the best would be if the
authentification be done without the client have more then a web browser
.A table with username password and associated Y is stored in a mysql
database in the LAN.
i am just looking to know if it can be done.And what kind of knowledge
would it require to have it done(what kinds of human resources should we
be looking to have it done.
Thanks.
