Hi Folks,
I need some help please, it seems I'm missing something but can't figure it out at the moment. I have identical sites using this setup and they are functioning fine.
My setup is a small branch with a cable modem, I have a Cisco 881 routers connected and have configured an ipsec vpn to my HQ. The tunnel is up both phase 1 and phase 2 but traffic is not going over the tunnel.
The access list for the crypto map is being hit as I turned on logging, if I do an extended ping or trace using the svi on the router I get nothing. I have added the router config below

crypto ikev2 proposal MyProposal

Any help will be greatly appreciated.

No difference in hardware, only IOS image was different!!
And that was the issue as the upgrade resolved the connectivity.
