Thanks for the response! ...I really appreciate it. Correct, Once the tunnel is establishedd, I can successfully ping the interface of the downstream router (192.168.101.3) thats on the same broadcast domain as the client. Pings time out once I try to hit the gateway interfaces on that same cisco router (10.10.2.1, 10.10.3.1, etc...) Per your request, here is the requested commands on the ubiquiti edge router.

And just as a reference point, here is a 'show route' on the cisco router showing it's corresponding abilities to get back.

Will be more than happy to do a tcpdump, but it might take me a day or so (travelinng).
