  Figure 22-8 Network configuration example with a firewall installed on the HiRDB single server configuration side

  

In this configuration, the settings for the server and client machines are as listed below. When you install the firewall, you must set one of the following operands.

• pd_service_port operand
• pd_scd_port operand
• -s option of the pdunit operand

If only a firewall is installed, there is no need to specify the client environment definition (PDSERVICEPORT operand).

Server machine settings

• System common definition file
  set pd_name_port= 20000
  set pd_service_port= 20001
  pdunit -x hirdb01 -u unt1
  pdstart -t SDS -s sds01 -u unt1
  

Client machine settings

• Client environment definition
  PDHOST hirdb01
  PDNAMEPORT 20000
  PDCLTRCVPORT 30000^#
  
• hosts file
  172.16.0.10 hirdb01
  

#: Specify this when there is a firewall on the client side.
