Good job on solving the Checkpoint issue.   The reason you couldn’t use the /16 is because if you do then the subnets for both locations end up being 143.161.0.0, and you can’t have that if you want to send traffic between them. (Each octet in an IP address is 8 bits, so a /24 means the first three octets define the subnet, whereas a /16 means only the first two octets define the subnet).   If you’re using a /24 at each site, you have 254 available IP addresses per site, so if you’ve only got 20 devices (even 50) that’s more than enough. The VPN can work for all the devices on the network, but that depends on the routing being setup correctly, and the network segmented properly. ... View more
