I have to connect 2 VPN service at same time. one to be used as default gateway, and other for only tunnel behind NAT to manage that device from outside.
Openvpn works perfect fine (if only openvpn is connected) , no dis-connections, nothing, but as soon as i start the wireguard vpn ( i already have disabled its gateway feature so that it does not become default gateway), then openvn stops working, keeps saying it cannot connect to remote server.
How to make both work ? at same time
(they do work sometimes randomly though)
It’s a challenge to guess what you’ve got. If you post here, using the preformat button in the editor toolbar </> (masking any sensitive data, but not so much that the routes don’t make sense), you can probably get some good insights from the people here. I would post at least three conditions:
Now when i reboot router, then the routing table becomes like below. and there is no internet connection at all. I have to manually stop openvpn as well as wireguard, to resolve it.

Use one vpn at a time. Also you can setup one vpn on your router and another one on your device. In such way two vpns will works at a time. Here are setup guides : https://aeroshield.me/how-to-setup/
