No, that should be more than adequate. I have machines running 3.3
through 3.16 without a similar problem. I haven't been rolling my own
kernels, though.

It will likely turn out to be the same problem for all the errors,
so lets concentrate on ftp as that comes first.

Does the output of dmesg shed any light?

Is the NAT module getting loaded? Are you using NAT? The FTP conntrack helper
appears to be built in, perhaps try building it as a module?

Finally, I found this: https://dev.openwrt.org/ticket/13183
is automatic helper assignment somehow disabled in your kernel? I don't
know what the implications of that would be.
