I need to establish a VPN tunnel between office A and B. Bi directional support is required. Please see details below.
Office A is running a flat level IP Scheme with no VLANS. It's current ip scheme is: 10.1.198.0 /22. A microsoft threat management gateway is installed at this office. Only a small number of people need connectivity to office B. Around 8 people.
Office B would only like office A to access their /28 addresses over the tunnel.
What's the cleanest and best way to establish a tunnel between the two sites from an IP perspective? Office A will need to make a /28 range available over the tunnel, but instead of allocating the necessary users with static IP addresses on their workstations is there a better way to manage this tunnel?
Appreciate any advice and guidance.
