Issue with configuring NordLynx

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello.

Recently I installed OpenWRT on my Xiaomi Mi Router 4A (100M), so I could use my NordVPN on all of my devices at home.

I successfully configured OpenVPN, but when connected my internet speed drops drastically (8 Mbps from 50 Mbps). So I tried to config Wireguard using these guides.

I followed both of these guides and from my understanding did it correctly. But when I reboot my router, internet connection (through L2TP) doesn't seem to establish.

Hope somebody can help me with my problem.

Below are network and firewall config files:

You will need to add some additional routes so that raw packets will be sent to Beeline's L2TP server instead of the Wireguard tunnel. Also it appears that tp.internet.beeline.ru can't be resolved on the general Internet, so you will need a route exception to Beeline's DNS server-- or install the server as a numeric IP, assuming it never changes.

Thanks for a quick response.

Got to say my knowledge of networks is little to none. It'd be very helpful if you can point me to where and what do I need to change.

Quick update.

or install the server as a numeric IP, assuming it never changes

It definitely did something helpful, but I still have no idea what should i route and where to.

Appreciate the help.
