Would it work if we implemented DMVPN with 2 hubs at the same location but with each one connecting different ISPs? The hub routers will be behind ISP NAT boxes and the spokes in the remote locations will be using an ADSL modem. The spoke routers will also be configured as PAT and Firewall. We also want to connect the 2 hubs to the same LAN segment.
Does anybody have any configuration examples for DMVPN redundancy with 2 HUBs connected to 2 different ISPs and to the same LAN segment? We will need a hand with NAT configuration as well on the ISP NAT boxes.
