What terminal commands should I execute to understand why WAN connection fails after disabling the firewall?

config switch_vlan
	option device 'switch0'
	option vlan '1'
	option ports '2 3 4 5 0t'

config switch_vlan
	option device 'switch0'
	option vlan '2'
	option ports '1 0t'

Should be simple. Take the above and make it like this:

config switch_vlan
	option device 'switch0'
	option vlan '1'
	option ports '1 2 3 4 5 0t'

config switch_vlan
	option device 'switch0'
	option vlan '2'
	option ports '0t'
