Observe the following notes on the use of JP1/Software Distribution when using Internet Options:

• You cannot use packaging with HTTP Gateway.
• JP1/Software Distribution uses host names, IP addresses, and host IDs as the ID key for operations (key information for identifying nodes). JP1/Software Distribution compares the created job with the key for operations. If the NAT facility is used, the address is converted and the job is not given to the appropriate client. This is because the IP address of the JP1/Software Distribution Client (client) for the JP1/Software Distribution Manager differs, due to the NAT facility, from the actual IP address of the JP1/Software Distribution Client (client). In an environment using the NAT facility, you cannot therefore use IP addresses as the key for operations. We recommend using host IDs.
• When you use IP addressing, the IP address is used in the protocol and may be leaked. Therefore, if you are using a firewall, we recommend not using IP addresses.
• The automatic registration facility for the system configuration in JP1/Software Distribution uses the IP address in the protocol regardless of what key is used for operations. Therefore, there is a risk of the IP address used in the protocol being leaked if you use the automatic registration facility for the system configuration. If you are using a firewall, we recommend not using the automatic registration facility for the system configuration.
• To improve security with a basic firewall configuration, the general recommendation is a network configuration that separates the segment with the external public server (unprotected segment) from the private network. In most such configurations, communication is limited between the unprotected segment and the private network. To enable communication between the Web server and JP1/Software Distribution, set the filtering table of the firewall product as follows:
  IP address of sender: IP address of Microsoft Internet Information Services
  Sending port: 1024-65535
  IP address of receiver: IP address of JP1/Software Distribution higher system
  Receiving port: NETMDM
  Protocol: TCPEST
  Direction: in
  
• You cannot use the remote control facility via Internet Options.
