Support TCP on port 443

[EgidioCaprino]

Before creating this request I have:

REQUIRED

• Read through the pinned issues for related problems
• Searched for similar provider issues and container issues
• Read the documentation, especially the troubleshooting section and FAQ
• Tried to add as much relevant information to the request as possible
• Agreed that my issue will be closed if I do not follow this template and will remain closed until I complete the template

Is your feature request related to a problem? Please describe.

REQUIRED

Some ISP engages in bandwidth throttling. A workaround is to switch from UDP to TCP on port 443. More details here: https://mullvad.net/it/help/improve-slow-speeds-throttling/

Describe the solution you'd like

REQUIRED

I couldn't find any way to change the OpenVPN protocol and port. It would be great to have OPENVPN_PROTOCOL and OPENVPN_PORT environment variables.

Describe alternatives you've considered

REQUIRED

Creating a custom it_all.ovpn file and mounting it to /etc/openvpn/mullvad/it_all.ovpn

Additional context

Optional

None

all that is needed for this is to updated the vpn configs or as you did above, create a custom profile specifying the port.
Not really anything to be done on this container directly

[roberthinsom]

It seems that updating the VPN configurations or creating a custom profile that specifies the port is all that is needed, and there is no direct action that needs to be taken on the container itself. This means that any changes made to the VPN settings can be made outside of the container and then applied to the container as needed.

It's important to consider the impact that the VPN connection may have on network performance. Connecting to a VPN can sometimes result in slower internet speeds due to increased latency or bandwidth limitations. One can check net speed test online to confirm that either interent speed slowed down due to use of VPN or not. However, using a VPN can also provide additional security and privacy benefits that may outweigh any potential performance trade-offs.

If you are experiencing slow internet speeds while using a VPN, it may be worth testing different VPN configurations or providers to see if there are any performance improvements. Additionally, it may be helpful to test internet speeds both with and without the VPN connection to better understand the impact that the VPN is having on network performance.
