make sure nordvpn is main route for ethernet and wlan0

hello,

when using airdump-ng and airplay-ng

how do i know if kali linux is using nord vpn ip and making sure my real internet ip is safe? i know over ethernet when loading browser it shows nord ip

but when i use my ac realtek wifi usb in monitor mode.. and use airdump airplay how do i know its hidden behind nordvpn also whether enabled as managed or monitored?

here is what i get with traceroute and ifconfig.. is it already working correctly or no? If not how can i make sure no matter what Nord vpn will be default gateway or make it so my wifi usb isnt going to expose my real ip?

here ill paste my input below. im new to linux and this is just for fun ! It's practice. just being safe. trying to learn since im going into cyber sec field

nord vpn on kali linux with usb realtek wifi on m0nitor mode
