Hey Jerry, sounds like good progress.

There are a few, *if* you try http://jnoswiki.no-ip.org and you do not
find the answer, I am quite interested in hearing "what's missing" from
you.  I hope I have time to add the subject before I hand the wiki off
to it's new owner...

On the jnos stack end of tun?
May I presume 192.168.0.75 is used on the host stack end of tun?

Here is one issue: ...0.75 is not the jnos stack.
To be equivalent to DOS, the DMZ target needs to be ...0.55.

You might end up happier if you used "pinholes" rather than "DMZ".
That is a firewall consideration for your site.

There is a guy who hangs around these parts who often says: "Think like
a packet." in situations like these.  His advise can be effective when
you are looking at all the details.  Like:
  1) is the Internet gateway IP defined in jnos route just like the IP
in the host route?
  2) is IP ...0.55 defined in the route table at ...0.75 host?
  3) etc
