FlexVPN vs DMVPN behavior. Advice?

Advertisement
So I'm testing FlexVPN and I've found, for me anyway, a pretty big deal breaker.
I can't ping, telnet, connect to in any way (other than routing protocol,which works fine), the "directly connected" network.
What I mean by that is say my Tunnel interface is 192.168.254.2 on one of my spokes, I can't connect to my hub at 192.168.254.1 or another spoke at 192.168.254.3.
Day to day this wouldn't be an issue but sometimes in the event of a network outage I need to be able to get in via my VPN backdoor.  So I'd go to 192.168.254.1 and telnet to 192.168.254.3 and wallah I'm in.  DMVPN this worked great and saved my bacon many times.  With FlexVPN this option is no longer available to me best I can tell.
Is this known behavior?  Is there a fix? Am I just doing something wrong?
Thanks

Ping will automatically use the IP address of the interface the request is leaving from, but just for grins I went ahead and tried sourcing it explicitly.  No change. Again, keep in mind, EIGRP works fine.  So neighbors are forming between these Tunnel interfaces. Just no other traffic.  Here's the commands I used to add FlexVPN to my router:
ip access-list standard Flex-Route
permit any
crypto ikev2 authorization policy default
route set interface
route set access-list Flex-Route
crypto ikev2 keyring Keys
peer Router
  address 0.0.0.0 0.0.0.0
  pre-shared-key X
crypto ikev2 profile FlexVPN
match identity remote address 0.0.0.0
authentication remote pre-share
authentication local pre-share
keyring local Keys
