[Nottingham] Tunneling question.

[Colin Saxton]

Just thought I would ask you guys this question...

I have a setup with a DMZ area. In the DMZ area I have an application
server that needs to communicate directly with a DB server behind the
DMZ. I could open the port through the DMZ to the DB so that the
application server can see it but I don't won't to do this directly.

Is there any software out there that would do the following.

1. Open the port from the DB server through to the DMZ and connect to a
** waiting ** client proxy. I mean waiting because the client would not
be able to connect through the firewall to the DB.

2. Once the client has a connection from the server then any clients
running within the DMZ could connect to the client proxy and tunnel
through to the server. Both the client/server proxy would use SSL

I thought I would ask before are start coding something like this!

Regards,
