do i need to disable DCHP and Disable NAT before i call isp provider to switch my isp router modem to bridge mode or is it automatically disabled with switching to bridge mode i cant find on my router modem where is nat functionBut to get it working for now just disabled DCHP and NAT on the modem/router. Then the only thing that will be plugged into the modem is your new router that's running the VPN. Everything else on your network will be connected directly to your new router.
