need some help connecting a cisco 800 at home on a dynamic IP to the
office Sonicwall.

If i statically assign an IP on the sonicwall SA and set it to Main
mode, it works.

soon as i change the sonicwall gateway to (for dynamic) and
set aggressive mode, i get the following

IKE Responder: IKE proposal does not match (Phase 1)

any ideas?
