Ideally your physical server connecting to  switch port must
have configured with atleast 1600 MTU in order for VXLAN
traffic to work seamlessly.

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,

Martins
