we are getting new sip trunks put in and in order for the provider to put them in the Providor put in a router to control all web traffic so they can QOS the voice that means our VPN routers will go behind the nat barrier. but when i switched the routers interface to the natted address the DMVPN tunnels would not build. there is a nat translation to the routers so the external(route-able) IP did not change. the IPsec tunnels did come up just fine. just the few DMVPN connected tunnels did not.
if issue a "sh DMVPN" the Peer NBMA Addr shows up as 0.0.0.0 while the Peer Tunnel addr is what it should be, also the attrb is "X"
Tunnel source i have set to the interface, and the key is set to "crypto isakmp key "my key" address 0.0.0.0 0.0.0.0 no-xauth"
i am at a loss on why this was not working. keep in mind this is the HUB router and not the Spoke.
