OpenVPN & NordVPN on R6220 - no internet & RX =0

Installing and Using OpenWrt
1

HI All,
I spend few days with configuration OpenVPN and NordVPN. Till now I cant establish internet connection.
I've installed OpenWrt 19.07.6 and OpenVPN and tried several instructions/protocols/servers, and always connection logs shows that I am connected to VPN but without access to internet. I can't ping any IP.

Any suggestions will be very helpful

Make sure to download the latest client config from the VPN provider site.

Optimize MTU on the WAN interface and enable MTU fix for the VPN zone:

uci set firewall.@zone[2].mtu_fix="1"
uci commit firewall
/etc/init.d/firewall restart

If the issue persists, activate the VPN connection and post the output to pastebin.com:

ubus call system board; uci show network; uci show firewall; uci show openvpn; \
ip address show; ip route show table all; ip rule show; iptables-save; \
head -v -n -0 /etc/resolv.* /tmp/resolv.* /tmp/resolv.*/*
