Hi Darren, this seems to be closely related to IPfilter, can you please have a look?
When hardware checksumming had been disabled; this problem does not appear when the
checksumming is enabled no packets are being allowed (as mentioned in the ticket);
I can succesfully reproduce the problem, if you need additional help let me know!
