Incoming connections disappear when I turn on VPN

[dragospirvu75x]

Hello everyone!
In a nutshell, I want to run UA Cyber Shield with VPN ( https://prnt.sc/MkuKxSEz7YrB ) because is more efficient but it has negative effects on other applications when I turn on VPN, including Bitcoin Core (I can't get incoming connections anymore). When I turn off the VPN, all apps (including Btc Core) automatically start working properly.
How do I solve it? I don't have a favourite vpn brand, I just want something to work with full node and preferrably cheap.
No political discussions, please.
Thank you!

Assuming you use a shared VPN, it won't forward the default port 8883 to your computer. Depending on your VPN provider, you may be able to forward that port (or set a different one). My favourite VPN has instructions for it.

Suggestion: if you want to use the VPN for only one specific application, can you run it in a VM?

And on the other side some firewalls, both hardware (sonicwall) and software (mcafee) may block known VPN IP addresses for incoming connections. I can't speak to others but I have seen it with those products. Having nothing to with BTC but it should follow the same rules as other apps. So you may go out but others might not let you in.

Well, I guess I can do it, thanks for the idea.

Maybe it can be a cause, I will consider that. Thanks!

Make you have sufficient resource to use VM which run Bitcoin Core.

The idea is to keep Bitcoin Core outside the VM.

I will run the other program which requires VPN on VM and keep Bitcoin Core on the main OS.

But my suggestion still applicable for general application.

Of course, thanks!
