i have configured PPTP connection in network setting of my Archer A9, now when i use NordVPN i can ping to the websites but i can't open any website in browser(s) i tried everything by changing browser, DNS even used openVPN app to connect with nordvpn server but still facing the same problem (CAN'T OPEN WEBSITES IN BROWSER)

after some google search i found that i have to check the vpn pass through option in wifi router but even after enabling it the problem still not resolved

is this due to my ISP is providing me internet by using PPTP ?

and i can't use vpn on vpn

i also tried configuring my nordvpn username/password on wifi router (internet section) but was unsucessful in that

please guide me what could be the possible reason
