In message <199806041437.OAA28931 () paranoid eltex spb ru> you write:
SQL*net? are you sure?

In SQL*Net Version 2, there is a mode (eg. when running multithreaded
servers) where the primary listener tells the client ``call me back at
ip a.b.c.d port xyz'' and hangs up.  The client then sets up another
connection to the specific listener process (at the address and port
as specified).

This is tough when going throug NATs.

As Oracle claims to do some packet signing, it gets even tougher
(havn't verified that they really do it).

An application level proxy is available from Oracle (and some
firewall vendors) which supports this mode with address hiding.
