I need some helping setting up my home network

[MileHighMT]

My home network is very basic and is set up like this.


It's all default settings. The R7000 router is set to be a DHCP server with starting IP address 192.168.1. 2 and ending address 192.168.1. 254 (spaces so reddit doesnt make those a link).

I have a couple of VM's on the server and I am trying to figure out how to get the VM's to have internet access.

I have been following this video but every time I try to start the virtual switch, it does something to my physical router and takes down the internet for my entire house. The only way I can figure out to get the internet working again is to hard reboot the router.

I dont want to do anything fancy. I'd just like to get the VM's online to do some basic stuff like host dedicated game servers and do a media server. Obviously I need to try to do this in a way that provides some security. I realize I may need better equipment and I'm not opposed to purchasing something, but I've been told I can make a "flat" network with what I have and it should work for what I want to do.

I really need some help getting this going. I'm not sure what to do. I'm pretty new to networking and servers so this is all a learning curve for me. Can someone point me towards a video or write up that will help me get this set up and working? Or, if you fine people care to take the time, giving me instructions will also work and be much appreciated.

TIA!

A virtual switch won't cause problems like that on its own. Do you have any VMs that have DHCP servers running or the likes?

As for your hardware, you don't need to purchase anything extra. All that's really required is for you to set up port forwarding (and/or enable UPnP) on your router for whatever ports you want to the corresponding VMs they should go to. By default, all outbound connections should be permitted on your router, so, all your VMs will have internet access, they just won't have any incoming connections permitted until you set up port forwarding.

I only have one VM right now and it doesnt have anything on it cause I couldnt get past getting it online. I dont think its running a DHCP server unless its doing that by default (which I am doubting).

Do I even need to set up the virtual switch to get internet access to the VM?

I'm using Hyper-V for what its worth.

You will need at least one virtual switch, otherwise your VMs aren't going to be communicating with anything over the network (even internally).

Do you still have the same issue if you create a virtual switch while your VMs are powered off?

I have not tried this so I will have to. I've got family around for the holidays so I'll hae to wait for a good time to test it cause if it does take the internet down, it takes an annoying amount of time for it to come back up and I dont want a bunch of grumpy family members cause I killed their internet.

Thanks for you assistance.

If a VM ends up with the same IP as the router (presumably 192.168.1.1) then that will also break things.

I've created a new virtual switch in Hyper-V and have been able to start it with the VM turned off and everything seems to work fine. I changed the settings of the VM to connect to the virtual switch but it is not getting online.
