<br>
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>
