I have a E750 Mudi router, which connects to my OpenVPN provider without any problems. However my computer which connects to the router, is then unable to connect to its own OpenVPN. When I look at the logs on the computer, there is some TLS handshake problem. When I disable the VPN on the router, the computer is then able to connect to its VPN. Why is the gl.inet router VPN blocking other devices from using their own VPN?
I want to essentially do a double VPN, one VPN on the router level, and one VPN on the computer level. This should be possible.
This is supposed support double VPN run at same time in the different devices.
May check the MTU of VPN in the PC and router, surely that is the PC < Router.
Can you explain what you mean by MTU of PC < Router?
Another clue is, when I disconnect the VPN on the gl.inet router, I can immediately connect to VPN on the computer. This means the VPN on the gl.inet router is definitely blocking the computer VPN.
The computer is trying to connect to VPN with UDP port 443, is this port being blocked by the gl.inet VPN somehow?
I changed the gl.inet VPN from OpenVPN to Wireguard, and still have the same problem.
Do you use any special VPN routing policies? Maybe your VPN (you want to connect to) does not like the current VPN service? Double VPN might be not supported by all providers.
I bought another VPN and tested, and found out the problem was my previous VPN. The new VPN allows double VPN at the same time with gl.inet router.
