                          I have problem to setup PPTP VPN behind
                          floating IP's in instances which have VXLAN
                          network. Maybe someone had same issue and can

                          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
