6500 running BGP w/ SPA-IPSEC-2G

We are having trouble bringing up some IPsec tunnels on a 6500 w/SPA-IPSEC2G (which also has BGP and HSRP running).

The B side can ping us and it establishes the tunnel, however when it is established, they can't ping our devices, and on our side we can't even generate interesting traffic to bring the tunnels up.

As the tunnel does come up, I don't think it is a IPSec issue but rather a routing or access-list issue, I think the problem is that the IPs we are trying to ping are public IPs which are also visible on the global routing table, so when we run a traceroute, it leaves via an upstream, but fails en-route.

I'm sure I am missing something quite simple. Any ideas?
