Incomplete ESP translations

hi, i got this issue, source coming in via Tunnel needs to be NATed to 1 pool of IPs, this Pool is then allowed in my FW to access VPN. I'm seeing this error,

Incomplete ESP translations:

0 esp_conn=0x646757C0, hanging off nat entry 0x647CB8FC.

Anyone can explain why?

=========================

interface Tunnel1

ip address 1.1.1.1 255.255.255.252

ip nat inside

interface FastEthernet0/0

ip address 2.2.2.2 255.255.255.0

ip nat outside

Hi

Do you have NAT Traversal enabled on this router, which version of IOS are you running.
