How does the name server handle services which require all machines to be DNS registered?
There is a common problem with firewalls that implement dual name servers. Some Internet services require that every machine which contacts them be registered in the domain name system. For example, if you FTP to ftp.uunet, you will not be granted access unless the machine you are FTP’ing from has an entry in the DNS. Many firewalls that implement dual name servers do not handle this situation well. BorderWare handles this situation easily. BorderWare is a true application level proxy; all IP packets leaving your organization have a source address of the Borderware firewall itself even if the packets originated deep within your internal network. And since the BorderWare server is registered with the DNS, all Internet services will properly validate it.
