[Solved] NAT sharing problem

Hello,

I have a gateway with three interfaces; WAN (192.168.15.2), LAN (10.10.10.1) and WIFI (172.16.0.1).
Internet connection is ok on gateway (WAN is connected to CPE Wimax).
From clients (PC via LAN or Android via WIFI) I get IP delivered by the DHCP gateway.
I can ping 10.10.10.1, 172.16.0.1 and 192.168.15.2 from PC and Android but I can't access to Internet

# iptables -nvL
Chain INPUT (policy ACCEPT 38881 packets, 6541K bytes)
pkts bytes target     prot opt in     out     source               destination         

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target     prot opt     in     out        source               destination         
    0     0       ACCEPT     all  --    *        *           0.0.0.0/0            0.0.0.0/0            ctstate RELATED,ESTABLISHED
    0     0       ACCEPT     all  --    WIFI  WAN      0.0.0.0/0            0.0.0.0/0           
    0     0       ACCEPT     all  --    LAN   WAN      0.0.0.0/0            0.0.0.0/0           

Chain OUTPUT (policy ACCEPT 56973 packets, 29M bytes)
pkts bytes target     prot opt in     out     source               destination
# cat /proc/sys/net/ipv4/ip_forward
1

Someone have an idea of what I need check?

Thanks

When in doubt, check the wiki https://wiki.archlinux.org/index.php/Internet_sharing

Re: [Solved] NAT sharing problem

You were right ROOKIE, I read too fast.
IPForward=ipv4 in [Network] section of /etc/systemd/network*.network
