Windows VPN client can't get through pfSense w/o pfSense restart
« on: December 14, 2017, 09:54:01 am »
My Windows VPN clients (PPTP) cannot VPN to an outside network via the Windows VPN client without a pfSense reboot.

Windows 10 goes through the steps of connecting. But when the "Completing Connection" status should appear, it's shows no message and eventually fails. Restarting Windows, and problem persists. Restart pfSense, and problem goes away.

Some info:
* The Windows are VMs on a Linux box.
* Behavior observed in Windows 10 and Windows 7.
* One VM uses Cisco AnyConnect and exhibited no problem using that client. (It's connecting to a different outside network.)

This behavior seems to have started a couple of pfSense versions back.

Side note:  PPTP was publicly known to be insecure no later than December 2004.  Can I ask why you're still using it in ~2018 instead of a commercial TLS VPN, OpenVPN, or IPsec?

It could be a service that stops working and once you restart, it restarts the service and VPN works. First off, start using OpenVPN. Also if possible, provide the logs. I had seen similar issues with UBNT where the vpn service itself goes stale and a restart of service fixes this issue.
