I have a Hyper V Server 2016 installed with a virtual machine that has the RRAS installed.
I cannot seen to connect externally to the RRAS server from any device I have setup initially the PPTP VPN on the VM and can connect from other VM's on the same host but cannot connect from machines outside the network or other machines internally that are not on the host... I am going to move to an IPSEC VPN soon but just cannot seem to get the PPTP VPN tunnel to connect. It seems to fail at the GRE level.. I have even turned the host and VM firewall off Originally the VPN was on another older server that was not virtual so I know the firewall rules are OK Any ideas?
This looks like an issue with your Hyper-V switch on the host.
I have recreated the switch on the host and still the same... seems really strange
