I currently own a huawei p8 I need to know how to disable vpn for minecraft?

VPN is set in your PC, not in the router.
Disable any VPN in your PC. If you have no idea what VPN you have, or do not know that you ever installed any VPN, then that suggests you have a virus/malware that has set a proxy to some hacker's web server. In that case, do a full virus scan.
