How to expose the Devstack floating ip to the external world?

Question

To this project, my hardware configuration is a host ESXi 6.7 (OS boot USB 8GB), i7, 8 vCPU, 16GB RAM, 128GB SSD and 500GB HDD.
And I created a single vm (7 vCPU, 15G

Answer 1

Well, after 5 days of research, lecture and harassment from stackoverflow reviewers, I found those lines to solve my problem:

echo 1 > /proc/sys/net/ipv4/conf/ens160/proxy_arp
iptables -t nat -A POSTROUTING -o ens160 -j MASQUERADE

Openstack VM is not accessible on LAN

Good Luck.
