Hi,
I'm running DMVPN together with IPSEC with on a Cisco 1941 with the (new) ISM VPN Module.
My problem is that when I enable the ISM VPN module, then the DMVPN tunnels refuse to come up.
ISAKMP is OK, the IPSEC tunnels are OK, but there is no outgoing traffic through the DMVPN tunnels.
I've recently upgraded to IOS 15.4(2)M1, this didn't solve the problem.
My only solution is to disable the ISM VPN module with "no crypto engine slot 0", then reboot the router.
And then all the tunnels come up...
Has anyone else experienced similar problems?
