    SNBForums is a community for everyone, no matter what their level of experience.

    The rules are simple: Be patient, be nice, be helpful or be gone!

Code:
ip a | grep global | awk '{ print $7 }' | head -n 1

This gives me:

eth0
 
@chongnt ... what does this give you?

Code:
ip a | grep global | awk '{ print $7 }' | head -n 1
 
Code:
admin@RT-AC86U-DBA8:/tmp/home/root# ip a | grep global | awk '{ print $7 }' | head -n 1
br0
admin@RT-AC86U-DBA8:/tmp/home/root#
What does this look like on your end?

Code:
ip a | grep global | awk '{ print $7 }'
 
Here you go

Code:
admin@RT-AC86U-DBA8:/tmp/home/root# ip a | grep global | awk '{ print $7 }'
br0
wl1.2
vlan500
scope
Hum so where's the ppp0 interface!?
 
@chongnt ... before we go chasing down this rabbit hole... could you please give me your results for:

Code:
nvram get wan0_ifname
nvram get wan1_ifname
nvram get wan0_pppoe_ifname
nvram get wan1_pppoe_ifname
 
Here you go

Code:
admin@RT-AC86U-DBA8:/tmp/home/root# ip a | grep global | awk '{ print $7 }'
br0
wl1.2
vlan500
scope
try
Code:
ip a | grep inet | grep -vwE '\b(((10|127)(\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)){3})|(((172\.(1[6-9]|2[0-9]|3[0-1]))|(192\.168))(\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)){2}))\b' | grep global | awk '{ print $7 }' | head -n 1


Thus why i said the route method is more efficient.

Code:
route | grep default | awk '{ print $8 }'
 
Hum so where's the ppp0 interface!?
ppp0 is from this
Code:
route | grep default | awk '{ print $8 }

Code:
admin@RT-AC86U-DBA8:/tmp/home/root# route | grep default | awk '{ print $8 }'

vlan500
admin@RT-AC86U-DBA8:/tmp/home/root# ip r | grep default | awk '{ print $5}'
ppp0

admin@RT-AC86U-DBA8:/tmp/home/root# nvram get wan_ifname
eth0
admin@RT-AC86U-DBA8:/tmp/home/root# nvram get wan_pppoe_ifname
admin@RT-AC86U-DBA8:/tmp/home/root#

for my ISP, internet is via vlan500. My isp use different vlan for video and voip.

See that is where you experience a rock and a hard place. See how asus reports the nvram variables as well.. this is interesting and highlights some of the foreshadowing brought about by @dave14305 .

So in your case, if I am able to match WAN0 to your vlan500, that should work...
