We are setting a hub (Point A) to spoke (Points B, C and D) VPN
The Hub is a Cisco 1760 with static public address
The spokes are Cisco 827H routers with DYNAMIC public address
We have no problem establishing the tunnels between the spokes and the hub, the problem is that the spokes don't talk to each other.
We can't define static routes at the hub because the spokes have dynamic addresses
We think that the solution is to use DMVPN and NHRP but apparently this features are not supported on the CIsco 827 routers.
Any suggestion ??
