How to use TCP 443 for openvpn on GLX750 Router

[selsherif]

Hi,

I’m using GLX750 LTE/$G Router and want to use TCP 443 port for openvpn connection. Can this be done on this router?

Thanks

Pretty sure it should work the same as in the other topic you already asked

OpenVPN TCP Port 443

A few months older thread, but I was able to get OpenVPN on my Brume 2 to use TCP/443, but I did it manually after looking through this and other threads here. I successfully used TCP/443 during my trip to Europe to connect to the Brume 2 OpenVPN server from whatever network I was connected to including my cellular WiFi hotspot. and even from a cruise ship’s network. I replaced the 443 listen port parameters in the /etc/nginx/conf.d/gl.conf file from 443 to 4433 using SSH and the vi text edito…

–
But not for incoming connections mostly, since you use LTE/5G.

I’m not using openvpn server, I’m using openvpn client and loading the configuration file from expressvpn. Here there is no option to change protocol or port!

I have no idea if I can/should use openvpn server with expressvpn!

Thanks for help!

You can’t change the port to 443 if you use only the client.
The port is provided by the OVPN provider - if they don’t offer connection to 443, there is no option to do it.

thanks for the clarification. I’ll try to contact them and ask if they offer this.

@selsherif

expressvpn

Let me suggest you https://mullvad.net/ - they are pretty good and offer OVPN TCP/443 support.

thanks admon,
I just purchased a mullvad account and tried it out, somehow it’s still not working, I have installed the openvpn configuration file (with TCP 443) from their website, added a new openvpn client to my GLX750 router and uploaded the config file and entered the user/pass. When I connect it show an error that it can’t connected and then this:

Socket Buffers: R=[87380->327680] S=[16384->327680]

Uhm, looks good to me. No error shown.
Ping does not work?

[selsherif]

no, I get timeout error:

Could you try to use OVPN on your PC/smartphone - just to make sure that it works normally with your ISP?

[selsherif]

on my iphone, only wireGuard works when I opt-in the “EireGuard obfuscation” obtion, this option hide the wireGuard traffic inside another protocol. But this feature sadly doesn’t exist when setting wireGuard on the router!

So you are currently inside a country with blocked VPN usage?
In that case it will be difficult.

You should go with the “bridge” servers listed here: https://mullvad.net/servers
And make sure to read this article: Intro to Shadowsocks | Mullvad VPN

It might be impossible to run it directly on the router - I can’t tell for sure.
