No internet connection in hyper v

Nurdauelet — Mon, 21 Oct 2024 14:56:42 GMT

I complely have no internet access to internet with my topology hosts. Just no internet to test that some specific sites are blocked or not. Let me show you topology. I did some policy rules for A-host. To test i have no internet connection in my hosts lol.
Please can you help what is the problem and how to connect my hosts to internet. If the problem is about virtual network switch. A host has only one which is A-INT-NET. Which is internal virtual network switch. Idk how to fix and back Internet access.

In other hypervisors, you typically need a VM that is bridged/NATted to your physical NIC somehow.
This appears to be how you achieve that in Hyper-V: https://learn.microsoft.com/en-us/answers/questions/336534/network-bridging-with-hyper-v-virtual-switches

The topology map shared is the CCSA R81.20 topology map.

That is in the CCSA book but it is also made available as a separate document without the DRM etc. so it will be out there to be found and maybe used as a Check Point reference topology.

The CCSA manual does not guide students through building the lab because ATCs must supply the lab, so it seems to be a lab build 101 effort.

There are some good resources out there, as well as what I already shared.

Snimak ekrana...I understood that, though I can barely write cyrilic anymore, haha.

Anywho, link Phoneboy sent is probably your best bet, I would absolutely follow that.
