provided scenario involves creating a virtual network between two hosts (A and B) using VXLAN.

On host A (assuming 172.16.71.2 with tun1 interface):

ip link add vxlan71 type vxlan id 71 remote 172.16.71.1 local 172.16.71.2 dstport 4789 dev tun1
ip addr add 172.16.171.2/32 dev vxlan71
ip link set vxlan71 up
ip route add 172.16.171.0/24 dev vxlan71

On host B (assuming 172.16.71.1 with tun1 interface):

ip link add vxlan71 type vxlan id 71 remote 172.16.71.2 local 172.16.71.1 dstport 4789 dev tun1
ip addr add 172.16.171.1/32 dev vxlan71
ip link set vxlan71 up
ip route add 172.16.171.0/24 dev vxlan71

When trying to ping 172.16.171.1 from A, the ping is not successful. image

(I am not really familiar with vxlan)

But seems like you are using the same ip as both underlay ip (tinyfecvpn) and overlay ip(vxlan)?

likely it's your configuation problem.
