Both my Hong-Kong no-name and Edimax EU-4208 seem to behave the same. This works with natd on RELEASE as well, but just for a limited time. I've yet to establish if it's time or #packets that cause the processing to stop. I'll try to generate some tcpdump output and compare working / non-working connected to NIC with txcsum/rxcsum disabled. Any pointers how to dig deeper? Kind regards, Spil.
