Add translation of ipcomp to nftables. First value of the parameter 'ipcompspi' will be translated to 'cpi' parameter in nftables. Parameter 'compres' is not supported in nftables. Examples: $ sudo iptables-translate -t filter -A INPUT -m ipcomp --ipcompspi 0x12 -j ACCEPT nft add rule ip filter INPUT comp cpi 18 counter accept $ sudo iptables-translate -t filter -A INPUT -m ipcomp ! --ipcompspi 0x12 -j ACCEPT nft add rule ip filter INPUT comp cpi != 18 counter accept Signed-off-by: Laura Garcia Liebana <nevola@gmail.com> --- extensions/libxt_ipcomp.c | 13 +++++++++++++ 1 file changed, 13 insertions(+)
