Can't ping across IPsec VPN from 867VAE-K9 to Cradlepoint IBR650

Level 1

I'm building multiple IPSec VPNs over cellular networks using a Cradlepoint IBR650 on either end.  On the head end is the 867VAE-K9 behind one of these Cradlepoints terminating one end of every tunnel and each other end is another Cradlepoint terminating the other end.  Currently, I'm trying to get one of these tunnels up and so far it has been a challenge.  I've managed to get what looks like to be IKE Phase 1 and 2 both at the complete stage and my show commands are showing UP-ACTIVE for Crypto Session and QM IDLE ACTIVE for Crypto ISAKMP SA yet I can't seem to ping the machine on the other end.  Can anyone give me their thoughts or requests?

Start with checking IPSec SA using show crypto ipsec SA command to see if
the encrypt or decrypt counters are increasing. This will show you whether
the traffic is leaving your router and not coming back or not leaving at
all. This way you know where you need to look.

Sorry for not getting back to you earlier.  I had this set up to email me when I had a reply, but that didn't seem to work.  All counters stay at 0.  Looks as though it's not leaving the Cisco router.

I've included my run output and ipsec sa output for inspection.  Is there anything else you or anyone else would like to see?

Update...  (Rev 2)

From the machine hooked up to the Cisco router, I can ping the LAN gateway address across the VPN on the Cradlepoint, but cannot ping the machine address inside the Cradlepoint LAN.  When pinging the Cradlepoint LAN gateway, the ipsec sa output shows all the "encap", "encrypt", "digest", "decap", "decrypt", and "verify" counters counting up, but only "encap", "encrypt", and "digest" continue counting when I ping the machine inside the Cradlepoint LAN.

Do you have any suggestions?

 

Included are my new run and ipsec sa outputs as I have been changing things and trying to look at things at a different angle if you would like to look.

Looks like my issue was simply the Windows firewall as it put the network I was connected to into the "Public" domain.  Shut down the firewall and pings all around.
