Why my Virtual Machine have same Public IP with host system? (VMWare Workstation)

[blueskysorrow]

In short,
So I'm using vmware workstation pro to running my virtual machine. The host system is running win 10 and my 2 VMs running windows 11. Both of my virtual machine have different local IP addresses from each other and the host system. But I notice that their public IP address is same with my host system.

What I want
1. All my VMs have different public IP adress (to host system and each other)

Any solution?

Becasue they're all reaching the internet from the same internet connection, which the public IP is attached to. You won't have different public IPs without using VPNs on each.

You either need a VPN on every VM or to buy a block of addresses from your ISP. Otherwise you're behind a single public IP address using NAT (or CG-NAT)

"Buy a block of addresses from your ISP"  that's sound new to me. I will ask my ISP for that. Thnksss

Huh, because guests use host's internet connection lol. Hypervisor just NATs the host's internet. If you want a different address then either ask your ISP if they can provide you with secondary public IP and then configure one on the guest, or use VPN.

The most common workaround to this is to get yourself a domain name, if needed setup DDNS then use a webserver to divide the domain up into virtual subdomains.

 

Doing this wont change the public IP but it will allow you to give each machine its own FQDN. For example on my domain I have mydomain.com as my landing page, pma.mydomain.com as my php,yadmin, plex.mydomain.com as a proxy to my Plex server etc etc. On my setup all my services are on the same machine so I can forward ports from my router to that one only, in your case you'd need to run the webserver on each machine with a different port for each then forward the relevant port from your router to the corresponding machine.

 

Edit - Thinking about it, if you were to buy a domain that supports DDNS (AFAIK almost all do) then you could create subdomains directly in your DNS zone using CNAME records.

 

Can I ask why you need this though?

[Kilrah]

Yep, doing the same here with a reverse proxy and DDNSed subdomains.

 

He most likely wants to run multiple servers of the same thing from the same place. If you do the above and use different ports for each server with the reverse proxy redirecting accordingly, no issue.
