Hi,
Till to Version17.5, there is a mandatory field in the Business rule as Host Name and the same field is there in version 18 also. But there is not mandatory that you have to access web services using the same hostname only as it is in the V17.5. Here, If you will try to access using the IP address then it is allowing to access the webserver.
Accessing Server using the IP address.
Firewall Rule configuration.
NAT Rule for the same.
Can anyone explain that it is a bug or configuration issue or now Sophos Removed the mandatory field as Hostname?
