Hi,

While trying to use @nh I got nft to segfault:

root@h7:~# nft --version
nftables v0.100 (keith-alexander-filter)
root@h7:~# cat /proc/version 
Linux version 3.14-rc7-amd64 (debian-kernel@lists.debian.org) (gcc
version 4.8.2 (Debian 4.8.2-16) ) #1 SMP Debian 3.14~rc7-1~exp1
(2014-03-17)
root@h7:~# nft add rule filter output @nh,16,4 8.8.8.8 counter
Segmentation fault

I infered the syntax from src/parser.y:

payload_raw_expr	:	AT	payload_base_spec	COMMA	NUM	COMMA	NUM
payload_base_spec	:	LL_HDR		{ $$ = PAYLOAD_BASE_LL_HDR; }
			|	NETWORK_HDR	{ $$ = PAYLOAD_BASE_NETWORK_HDR; }


But may be I made a mistake, I could not find documentation.

Sincerely,

Laurent
