Amazon NAT is exactly why I've mentioned it, because on an Amazon
system, if you don't use the --interface option correctly
($INT_IP!$EXT_IP notation), you get exactly these kinds of write errors
that show in your log.

But these configs and this CLI line don't match the logs you posted
earlier. Is it also write errors you're getting with those?
