Setup WAN port on static ip mode.
Usage: $0 {wan|wan1|wan2} GATEWAY IPADDR/NETMASK[,IPADDR/NETMASK] DNS[,DNS] [-S] 
        -S # don't restart service
Example:
    $0 wan 172.16.139.254 172.16.139.250/255.255.255.0 8.8.8.8 -S # Set wan as static ip without default route.
    $0 wan2 10.1.1.1 10.1.1.3/255.255.255.0,10.1.1.5/255.255.255.0 114.114.114.114 -r 10.1.1.3 # Set wan2 as static ip with default route.
