Hi There,

We are trying to host our website on our own server in our own office.

The problem is the port 80 is using by an other service and we could not change it. And we are using Ubuntu as OS for all our VMs.

My question is, is that possible to make URL pointing to the same IP address but different port with 80?

How can we do that please?

Thanks!

Yes it will be possible, but I have not enough experience to give you any significant guidance.

Is this absolutely necessary? Hosting a web site in-house strikes me as a risk. If the site is compromised (which these days is not a rare event), you potentially have an undesirable someone with access to your internal network.

Google "vhost"; you will need to configure it on your router or webserver to redirect traffic based on target address to your server of choice:
ws1.yourdomain.com:80 > 192.168.1.10:80
ws2.yourdomain.com:80 > 192.168.1.11:80
ws3.yourdomain.com:80 > 192.168.1.11:8080

Or if you're happy to run your webservers on different ports without automatic redirection then just setup port forwarding on your router from your WAN IP to whatever internal IP's / ports:
123.456.7.8:81 > 192.168.1.10:80
123.456.7.8:82 > 192.168.1.11:80
123.456.7.8:83 > 192.168.1.10:8080

If it is on an alternate port expect people to have problems understanding what to type to be able to access it, and in many cases being unable to access it as proxys will often prevent access to other than standard ports.

A reverse proxy would do the trick. Have seen a number used but nginx would be my go-to for this.

thanks guys, I might still don't quite understand how to do this, but I guess it's possible though.

I will do some research, but if anyone here could give some further instruction, that would be great appreciated.

What other service is using port 80? It is a standard port for http so any non-http service using port 80 would be strange.

If it is a http service (such as a remote camera) but you need to direct your website traffic to the new server then you will need to have a reverse proxy that will look at the request and then decide to which IP in your network to send it.

If it's not a http service then things get a bit more complicated.
