Hi Tim,
Sounds a bit like what I hit about a week ago,

> interface Tunnel1
>  ip vrf forwarding XXX
>  ip address 172.31.255.45 255.255.255.252
>  ip mtu 1460
>  tunnel source Loopback0
>  tunnel destination xxx.xxx.xxx.xxx
> end

Try adding 'tunnel vrf XXX' as well.
Everything I have read mentions that this command defines which routing
table the router will use to reach the 'tunnel destination', but I had
similar symptoms to you (one way traffic) and this fixed me right up...

HTH

Thanks,
Aaron Daniels
