8800NL R2 2.52.d15 IPv6 Tunnel not working

8800NL R2 firmware upgraded from 2.52.d12 to 2.52.d15.
I have an IPv6inIPv4 tunnel set up with Hurricane Electric, this stopped working. I used test-ipv6.com to check.
The tunnel was then deleted and re-created, it was still not working.

I downgraded from 2.52.d15 to 2.52.d12, keeping the current configuration, the IPv6 tunnel is working again.

HI Pete

Can you email me a copy of your config (support@billion.uk.com) with the password set back admin, so our engineers can investigate.

If it's of any help, at least for some confirmation
I have a 8800AXL R2 running firmware 2.52 d15 (Not the NL version but I believe it's the same firmware)
and my Hurricane Electric IPv6inIPv4 tunnel is working OK
Output from test-ipv6.com :-

Test with IPv4 DNS record ok (0.071s) using ipv4
Test with IPv6 DNS record ok (0.096s) using ipv6
