We are have a Fortigate 60D attached to our network of 5 servers. The fortigate is freshly setup and has a policy that allows all internal servers to have access to the internet. This is specified by allowing all servers within the same IP subnet to have access.
What we are finding is that there is a odd number of IP's within the subnet that should have access to the internet that are being blocked. They can ping the gateway but cant go any further. There really isn't any other rules apart from allowing FTP access from external connections to an internal FTP server.
Any help would be greatly appreciated.
