I would also check that <Tableau Node>:443 works. Ensure that your load balancer is routing traffic as expected.
It looks like gateway.trusted is 3 ip's? Is that expected? tableau.example.com has 3 ip's or is that the list of your 3 Tableau Nodes? If its your 3 Tableau Nodes, it should be the IP of tableau.example.com

By doing above am I able to access tableau server from any public machine?
Possibly if your load balancer is reachable from the internet and your company's firewall & proxies allow it. If your TS is within your company's intranet then most likely not as it's a matter of security.
You should work with your IT department about this.
