We had a report about NAT failing to work in a similar situation
with HW checksums, but I couldn't find the reason. You could try:
- check if you have HW checksums enabled on the eth-device using
ethtool
- enable conntrack logging by loading ipt_LOG and executing
"echo 255 >/proc/sys/net/ipv4/netfilter/ip_conntrack_log_invalid".
- if this shows something about invalid checksums, disable HW
checksumming on the eth-device and try again
