Hello all,

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.

Best regards,
