Proxy between Lotus Notes Client and Lotus Domino Server

I would like to build a proxy between client and server, which
originally communicate on the 1352 port. Proxy should just tunnel
data, w/o any changes. Is this possible, and is there a link to start
from? How should I configure both client and server for this?

I'll repeat the question, just in case... If I'm in the wrong group
please let me know.

Try using the Stunnel software for this.

Why don't you just tick the box that allows Domino to create a VPN between
the server and client?

The reason is I want to create my own proxy between them. I kind of
hoped it will work if I just tunnel data in a generic kind of way, but
first experiments failed. In these situations you never know whether
you did something wrong, or it's plain impossible. That's why I'm
asking here.

But let's play along. Can I customize Domino's VPN (is there some VPN
API) with C++?

So we are thinking the same:
Normally replication traffic is not encrypted, but if either the server or
the client has the feature enabled then the traffic is encrypted both ways.
As the link now requires authenication and is encrypted I can justify
calling this a VPN.
The quality of the VPN is good but not state of the art.
Can you do better with what you propose?
Do you need to do better than what is natively offered?
To enable this at the client:
File/Preferences/User Preferences
Ports/select the port and tcik "Encrypt network data".
To enable this at the Domino server:
Type in "load notes" and follow the same process.
I hope we are discussing the same thing?

I want to include 5-step authentication with RSA keys on smart cards,
and encryption with any symmetric algorithm available. I already have
this for HTTP and FTP, as well as for tunnel proxy (or generic proxy).
Now I have a request to do it for Lotus Notes.

We need to have it under our control (source code an' all). If a need
arises where longer keys are required for either asymmetric or
symmetric encryption algorithm we can produce the code.
