Setup WAN port mode.
Usage: $0 {set|del} {wan|wan1|wan2|wwan} {dhcp|static} GATEWAY IPADDR/NETMASK [-d DNS[,DNS]] [-m metric] [-rRS]
        -d DNS[,DNS] # Manually add dns list
        -m metric # ADD metric
        -r # Add default route on this WAN port, It's default behavior.
        -R # Don't add default route on this WAN port

Example:
    $0 set wan -D # Set port 'wan' as dhcp mode.
    $0 set wan -D -d 8.8.8.8,9.9.9.9 # Set port 'wan' as dhcp mode with manual DNS settings.
    $0 set wan -D -m 60 # Set port 'wan' as dhcp mode with metric.
    $0 set wan -D -R # Set port 'wan' as dhcp mode, but don't set default route on it.
    $0 set wan -S 172.18.38.100 172.18.38.1/255.255.255.0 -d 8.8.8.8 -m 60 -R # Set wan as static ip without default route,and metric is 60.
