Hi Jason,

Hairpinning. So, set a router in there with a policy set on the
inbound ipip tunnel to forward all traffic out an ethernet to the ASA.
Then once I get it back on another ethernet from the ASA, use another
policy route to push it all to an outbound tunnel interface.

I hadn't considered that. Yikes, I'm not sure I want to. :)

Thanks,
Bill Herrin
