Re: Natting the traffic that comes through a tunnel

Use a loopback and use it to NAT both inside and outside. When combined
with your Tunnel the config may look a little complex at first, just keep in
mind what you are trying to achieve.

Contact me offline - it looks more complex than it is...

Ok - It is tricky.

But it will excite your sensibilities and probably enhance your ability to
take NAT and Tunnels to the twilight zone.

It is also quite eloqent as well and really kewlicious.

Strange enough, I don't recall seeing this any place in lab scenarios. I
could be mistaken.
