I don't think this will be a problem since DMVPN supports spokes behind NAT devices, but I'm planning on changing my network around for security and redudancy reasons and putting a pair of ASA firewalls on my collocation Internet connection. Right now I have a 3845 running DMVPN , NAT & ZBFW. I'm going to remove the ZBFW and move NAT to the ASA, leaving only the DMVPN hub and routing. If I create a static NAT mapping on my ASA to point to the DMVPN hub will this work?
I think it will, but I just wanted to be 110% sure.
That would be perfect, however, our 3845 terminates our p2p connection from our corporate office ((2) T1s bonded on a multillink interface). I would rather have all traffic pass in and out of the ASA pair, plus I'm not a fan of ZBFW after using it for a while. The ASA is so much better.
