Perfect. This would help immensely. Let me know when you have things up 
and ready for testing.

Very cool. I will do some prep work and read through the RFC a few more

The diagnostic output would be for ike not DHCP. I would at least expect 
to see an error message that describes the failure. Something along the 
lines of "exchange type 6 not supported".

If memory serves correctly, I believe its either the sonic wall or the 
juniper product line that supports mode config in push mode. I need to 
create a compatibility matrix on the Shrew Soft web site to document all 
this so it doesn't get lost in my head. Maybe a wiki would be in order 
as well for users that are kind enough to write some quick vendor 
platform specific notes or howtos.

Excellent. I look forward to working with you on this.

Interesting read. I may have to get in touch with them if I hit a bump 
in the road.

Thanks again,
