Hi, After updating my workstation from 4.4 to 4.8, which also serves as a NAT gateway for local machines, I noticed that TFTP across this NAT box broke: - TFTP read request to the server, source port 3534 - server replies with a data packet to dst port 3534 - gateway sends an ICMP destination unreachable with port unreachable along with the UDP data packet I am currently bisecting this, but it is taking a lot longer to build than I thought. Attached is the non-working case PCAP file for you to look at. There has not been a lot happening for net/netfilter/*tftp* between v4.4 and 4.8, so can you think about something in particular that could cause that? Thanks! -- Florian
