Three subnets and ip adresses needed
Sorry, the subnet of pc1 is 255.255.255.0 The subnets aren’t the most important part. You need to use different IP ranges on the NICs. Assuming that nic1 on PC1 is a public IP address, you need to use a private IP range on the other NIC such as 10.0.0.2 (and 10.0.0.3 for PC2) with a [...]

No, they shouldn’t be, unless you define the VPN connection to be created over multiple transports. ——————————— I agree with MrDenny: VPN tunnels are typically from host (IP) to host (IP).

Segmenting a piece of our Windows network
Your best option is to do some type of access control list (ACL) on the router or switch between the two subnets. In effect this is like creating a firewall rule blocking traffic between the subnets. ——————— As labnuke99 said: set up VLANs and ACL filtering on your router/L3 device to control traffic flows as [...]

Mac access list
I think your question is over-complicating things. I’d set up DHCP reservations (static IP-MAC bindings) that way the MAC’s are assigned the SAME IP every time they connect. Doing that would allow you to better control them with IP ACLs. Cisco DOES provide MAC filtering, but the DHCP reservation / IP ACL tends to be [...]
