I will answer in a Window context (I don't know *nix)

Since a UDF is a DLL, the UDF would acquire the user credentials of the hosting Firebird service.

The "user" which is typically used for standard installs is the "Local System" account, which has limited/no rights to external resources.

What you can do, is to assign specific user credentials to the Firebird service, once installed. Then as long as the NAS support CIFS shares and/or Active Directory integration, the UDF would be able to address the NAS resource. I doubt that the UDF would be able to access NFS resources, since it would not be able to password appropriate credentials (though I have never tried to)

P.S. This is really a support issue, as such it should be discussed on the Support mailing list ('Firebird-support@yahoogroups.com')
