[stunnel-users] using stunnel for smb networking

out of curiousity, has anyone been able to use stunnel as a cheap vpn for smb/cifs windows networks?

We have a stupid firewall policy that blocks ALL port 139 traffic. Yes, thats good most of the time since microsoft rpc's are notoriously insecure. It does cause a problem when we have other units at other universities with different firewall policies however, so I was hoping to go around the different bureacracies and tunnel it myself.

just curious.
