Are you actually running this?  I ask because I am wondering if it is as
complicated as it looks (I just downloaded the manual and glanced through
it).  I think setting up IP-NAT would be easier, although I could see uses
for this product.

The nice thing about NAT is that very few things don't just automatically
work; many of the seldom-used ports and protocols that DeleGate had to
hard-code into their product just function transparently through NAT.

Please tell me if I'm wrong, though.  And I find its claims that you can
tunnel IP between two DeleGate servers that are dialed into each other's
tty's extremely intriguing; there are certainly uses for that, I think.
