I’ve previously used a home router as a VPN gateway to my corporate network at AESTE. However, I’ve recently noticed that Ubuntu comes with its own PPTP client and I could use this instead while leaving the home router for devices that are not capable of connecting directly, such as a consumer NAS device at home.
I didn’t realise it but configuring it on Ubuntu was a snap. Just use the network manager and set the following settings:
Connection Name: Any VPN
Gateway: ip of the PPTP server
User Name: CHAP username
Password: CHAP password
Use Point-to-point encryption (MPPE): checked
Method: Automatic VPN
Use this connection only for resources on its network: checked
Add in any necessary routes to reach your private network.
