I don't know if it works under A/UX, but the VMS flavor of SQL*Net TCP/IP has a VALIDNODE config.ora parameter that lets you specify which nodes you will accept connections from.

That's OK, but I'd really like to see the ability to restrict connections based on the combination of node and username. That would make me more comfortable with allowing proxy logins across SQL*Net, which we do not currently allow.
