I have problem to setup PPTP VPN behind floating IP's in instances which have VXLAN network. Maybe someone had same issue and can recommend something? In security groups I allowed protocol's 47 traffic and VPN client can connect but it can't establish connection, I consider, maybe issue are with MTU, so VXLAN have MTU 1450, but if I watch ip link show, I can see that ppp0 interface creates with MTU of 1500.<br>
