We have servers at a hosting company. The subnet that the server is on has many servers belonging to others. We want to block connections to all the servers except our servers.
One method to do this is to put edit the scope entry of every allow rule to specify all the servers we want to allow access. This would be laborious. Does anyone have some automated way to update the scope of all allow rules?
Is there a easier way to block a subnet but allow exceptions for the servers you want to permit access?
