<body><div>opening any port on your firewall/edge router would make your IP open to probes tho, and you'd have to be sure the host you expose is secure so that other systems on your internal net isn't at risk. I guess you could place your host and guest on a separate vlan and place that into the DMZ with rules to allow internal to DMZ access to limit exposure. </div><div><br></div><div>Also make sure your router/firewall passwords are strong and not manageable from the DMZ. Dynamic DNS would mean you don't have to acquire a fixed external IP so you can then access via a DNS name rather than IP too.</div><div><br></div><div>Alternatively, make access via VPN only possibly with some of the above and not expose any open ports so you stay as invisible as possible on the web side...</div><div><br></div><div>hth</div><div>Dave</div><div><br></div><div><br></div><div><br></div><div>On Fri, 01 Dec 2017 22:07:17 -0000, Dan Gahlinger <dgahling@hotmail.com> wrote:<br></div><br><blockquote style="margin: 0 0 0.80ex; border-left: #0000FF 2px solid; padding-left: 1ex">

<div dir="auto">Dan, it is easy peasy, but not quite free, as if you want 24/7 access to the box, you have to keep the system running 24-7, so electricity costs. Plus, I’m planning on having others log in as well, thus I don’t want to open up my network like
that. That’s why I’m looking for a free hosted/Cloud solution. That way someone else can deal with the rest of the network security. I do enough of that for work anyway, don’t want to have to monitor my home network as thoroughly. </div>

<div dir="auto">Well, running from inside a house and making accessible from the outside is easy. But most ot my computers at home generally don’t run 24/7. </div>

<div dir="auto">Mainly what’s needed for what we both want to be able to do isn’t really a shell account on a shared machine, but literally a dedicated VM instance, but we need to be able to access that instance through a public IP address.</div>
<div dir="auto"><br>
</div>
<div dir="auto">On a home network, a private IP Address (192.168.x.x, 172.x.x.x ‘actually I don’t think it’s the whole 172 network’, or a 10.x.x.x) it’s easy enough to setup port forwarding to make it accessible. But on the Cloud based VM’s, I don’t know if
there is a way to do it. Well, I know there ARE ways, usually involves paying for the instance, an external address, and possibly the amount of traffic. </div>
<div dir="auto"><br>
</div>
<div dir="auto">Actually, I know Bluehost (is it still a thing?) used to give you a VM with public address in combination with their hosting/domain name service. But I’m hoping to find one that will not cost me anything. </div>
