Since March 2015 netfilter maximum table name length is 32 bytes.

Check if you're using UTF-8 as character set for the configuration file or for netfilter table names or if you're using non-ascii characters.

If so... each character takes 2 bytes and you're probably overflowing the max length of the table name.

btw, i think a similar length limit exists for target names themselves too.

I didn't add any custom table name. All table are created by openwrt default settings. The ipv4 tables are corrected.The ipv6 mangle/raw tables are corrected. Only ipv6 nat table wrong.

This happens when wan6 interface does not exist
