snat with dynamic ip address

["Lars Noodén" <lars.nooden@gmx.com>]

I have the following table within a NFTables rule set, but the address
given below (192.168.1.213) is assigned via DHCP and will change from
time to time.   How should I rewrite that line to do SNAT using whatever
the current IPv4 address happens to be at the moment?

table ip nat {
         chain postrouting {
                 type nat hook postrouting priority srcnat; policy accept;
                 ip saddr 172.16.3.0/24 oif "wlan0" snat to 192.168.1.213
         }
}
