I don't understand how vtun isn't what you're looking for?  I've used it for
setups very similar to what you're describing.

Perhaps a look at the vtun home page, which gives a better description
of what all vtun can be used for.
I've read the website and i figured that vtun is for binding two networks
together. The problems that i have is that:

1. My FreeBSD internal system is not doing routing/nat, it has only one
   interface with an RFC1918 IP on it. The router is an Allied Data 810.
2. My FreeBSD webserver doesn't have an inside interface, only an outside.
Neither of these points prevents you from using vtun.  Nor does either of
them make it any more difficult to use, really.  Actually, they're both
good reasons to use vtun.

Just set up your webserver as the vtun 'server' and the MySQL server as the
vtun 'client'.  Make sure to use TCP (not UDP) and things will work just

i'll try to make an ascii drawing of the situation :

| mysql server|--------
---------------       |          |switch|
                      |   |
                      |   |
--------------        |   |       
| imap server|---------   --------|router|
--------------                        |                           |
-----------                           |

I Hope this makes it a bit clearer, or you be able to tell me where i'm
wrong in this.
I'm not sure exactly _where_ you're wrong, but you are.  It can be done,
quite easily in fact.

What about your setup makes you believe that vtun can't create the connection
you want?
