to enable PPTP from Azure VM to on prem servers.
PPTP is a commonly used VPN protocol, hence it would be good to have it enabled in order to allow connections from Azure VMs to on premise systems.
Doug Lewis commented
PPTP would allow our developers on Macs to connect to our test machines. We're in a bind as well because Azure Resource Manager doesn't currently support ANY VPN technology.
We are forced to move away from Azure for part of our services requiring connect to client's PPTP/L2TP VPNs. This adds substantial risk and complexity to manage a multi-cloud setup just because of this.
