Access OpenWrt Router From WAN (SSH)

root@OpenWrt:~# iptables-save -c | grep Allow-SSH
[6:276] -A zone_wan_input -p tcp -m tcp --dport 22 -m comment --comment "!fw3: Allow-SSH" -j ACCEPT
root@OpenWrt:~#

It doesn't show a warnnig anymore but ressource unavailable.

I don't have a clue about what the messages at the left mean
