I think you want "mode transport" here


interface Loopback100

description LOOPBACK GRE

ip vrf forwarding CUSTOMER

ip address y.y.y.y 255.255.255.255

You might need the "crypto map" here; I can't remember

!

access-list 151 permit ip any any

I think this ACL is too broad; you just want to match GRE.


We do something very similar to this. Here is an example from our 2800 tunnel aggregation router:

crypto ipsec transform-set ts1 esp-3des esp-sha-hmac
 mode transport

crypto map cm1 local-address Loopback1
crypto map cm1 1 ipsec-isakmp
 set peer x.x.x.x
 set transform-set ts1
 match address 101

interface Loopback1
 ip address ....
 crypto map cm1

interface Tunnel1
 tunnel source Loopback1
 tunnel destination ....
 crypto map cm1

interface GigabitEthernet0/0
 description core
 ...
 crypto map cm1

access-list 101 permit gre host <Our IP> host <Peer IP>
