Important note: PPTP is obsolete, being not secure. Consider using other/more secure connection types like OpenVPN, WireGuard
- if you access your router from WAN and not from LAN, once connected to PPTP you won't be able to reach it. It will be reachable only from LAN.
- PPTP is an insecure VPN protocol. Don't use it to transfer sensitive data.
- Setting up a WAN connection via PPTP will route all your LAN devices through the VPN. If you want to use the VPN only for some of your LAN PCs/devices, try OpenVPN Client on DD-WRT with Policy Based Routing set.
