I have PI4 2gb.
I want to have vpn and adblock.
But, i also game online, will this vpn be good for online gaming?
That would depend on the game and platform. eg. The Steam platform expressly forbids the use of VPN's whilst gaming, primarily due to local censorship in some jurisdictions and price variations in geographic areas.
That would be a question you take up with your gaming platform, I know in the case of steam a lot of cheaters tried to get VAC (Valve Anti Cheat) bans overturned because it couldn't possibly have been their IP using the account (all attempts failed
What do you mean by using the Pi as a VPN?
