extensions: libipt_icmp: Add translation to nft
Add translation for icmp to nftables. Not supported icmp codes in nftables
are: network-unreachable, host-unreachable, protocol-unreachable,
port-unreachable, fragmentation-needed, source-route-failed,
network-unknown, host-unknown, network-prohibited, host-prohibited,
TOS-network-unreachable, TOS-host-unreachable, communication-prohibited,
host-precedence-violation, precedence-cutoff, network-redirect,
host-redirect, TOS-network-redirect, TOS-host-redirect,
ttl-zero-during-transit, ttl-zero-during-reassembly, ip-header-bad and required-option-missing.
Examples:
$ sudo iptables-translate -t filter -A INPUT -m icmp --icmp-type echo-reply -j ACCEPT
nft add rule ip filter INPUT icmp type echo-reply counter accept
$ sudo iptables-translate -t filter -A INPUT -m icmp --icmp-type 3 -j ACCEPT
nft add rule ip filter INPUT icmp type destination-unreachable counter accept
$ sudo iptables-translate -t filter -A INPUT -m icmp ! --icmp-type 3 -j ACCEPT
nft add rule ip filter INPUT icmp type != destination-unreachable counter accept
