Hi everyone, I'm running into a weird problem with RRAS/NAT on my Windows Server 2012 machine for my home lab. In my lab I have a private 10.0.0.x network that are hosted VMs. My hypervisor is running RRAS and NAT and is configured with one physical nic and 1 virtual Internal nic. The physical nic connects to my router that goes to the internet(192.168.1.0/24 subnet) and the internal nic connects to my private network.
In the RRAS management tool I use a custom config and select only NAT and LAN Routing. Now at this point NAT is not configured since I haven't assigned the internal and external interfaces. So from here I'm able to ping the 10.0.0.x machines from the 192.168.1.x network and vice versa. After I configure NAT with the external and internal interfaces, I am no longer to ping the 10.0.0.x machines from the 192.168.1.x subnet. However, I can successfully ping from the 10.0.0.x machines to the 192.168.1.x network.
I've also setup a rule on the internet router to route all 10.0.0.0 traffic to the physical nic of the hypervisor. Here's my current layout.
Internet
|
Router 192.168.1.1
|
Hypervisor - Physical nic 192.168.1.100 DG 192.168.1.1
- Virtual Internal nic 10.0.0.1 No DG assigned
|
VM Client - 10.0.0.4 DG 10.0.0.1
Any ideas as to why I can ping both ways when NAT is disabled but not when it is enabled? I'd like to keep NAT on that way my clients can connect to the internet for updates, but also accessible for remote login from the 192.168 subnet.
