Hi,
I have a project where several students with IBM SPSS installed need to connect to a server where the IBM SPSS Network License Manager (Sentinel RMS) is installed and it requires that UDP port 5093 be open on the server's firewall to allow the clients to communicate and retrieve licenses.
In my case this is not allowed in the firewall and I am trying to find solutions.

One solution is to create VPN users to ensure that only allowed clients can communicate on this port (UDP 5093).
But I prefer to keep the port closed for everyone.

So the question is of it is possible with stunnel to convert / wrap
e.g.
by users the UDP port 5093, to "convert" it to TCP e.g. 5555
thus bypassing the firewall policy on the server side (TCP/UDP 5093 is not allowed),
and on the server side to do the reverse, i.e. the "conversion" from TCP 5555 to UDP 5093

or is it a stupid idea? Has anyone done a similar project?

THX

John
