Restricitng access to a IP range
Posted on 2013-06-18
We have some PLC's at a remote site that use a 10.0.0.0 subnet. These are normally accessed via VPN by directly VPNing into the site. I would like to change this procedure, so the tech's that access these PLC's need to VPN into our main site and then be routed to the remote site.
So I don't have to get our ISP to doing any route changes for us I would like to change the PLC's ips to be included in the normal site subnet of 192.168.8.0/24. To do this I need to restrict access to the IPs we allocate to the PLC's.
So for example I would have a range of 192.168.8.200-210 for the PLC's and the only people that should be able to access this range would be a security group - PLC tech. Can I use either DNS or group policy to allow this to happen?
