I am trying to achieve sqlnet encryption without using Oracle ASO.

Client - Windows
Database Server - 9ir2 on Solaris (ssh enabled).

I tried configuring SecureCRT with port forwarding (on client). Am running into issues. End up with ORA-12570: Tnsacket reader failure.

The sqlnet tracefiles aren't being very useful.

Additional question: How do you deal with dynamic ips while configuring this?

Has someone else set this up successfully? Am guessing it's some trivial port forwarding setting that I've messed up.

PS: I've got things working with ASO..but it's too expensive. We want to do away with it.
