closely mirrors the existing ipv4 ruleset:
table ip6 io.systemd.nat {
set masq_saddr {
type ipv6_addr
flags interval
}
map map_port_ipport {
type inet_proto . inet_service : ipv6_addr . inet_service
}
chain prerouting {
type nat hook prerouting priority dstnat + 1; policy accept;
fib daddr type local dnat ip6 addr . port to meta l4proto . th dport map @map_port_ipport
}
chain output {
type nat hook output priority -99; policy accept;
ip6 daddr != ::1 oif "lo" dnat ip6 addr . port to meta l4proto . th dport map @map_port_ipport
}
chain postrouting {
type nat hook postrouting priority srcnat + 1; policy accept;
ip6 saddr @masq_saddr masquerade
}
}
Only difference is the use of ipv6 addresses instead of ipv4 ones.
Currently has no effect: all in-tree callers pass AF_INET exclusively.
Followup patches will make nspawn expose ipv6 too and rework
IPMasquerade option to support both/v4/v6.
