Here, a firewall and NAT are installed on the HiRDB single server configuration side as shown in the figure, with the two set as follows.

Firewall settings

• Direction: Receive
• IP address: 172.16.0.10
• Port numbers: 20000, 20001

NAT address translation

128.1.1.1 172.16.0.10

Note that HiRDB does not support a function that converts global and local IP addresses as a pair, such as NAPT (IP masquerade). It supports only 1-to-1 conversion.

In this configuration, configure the high-speed connection facility. The settings for the server and client machines are as follows:

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
  PDSERVICEGRP sds01
  PDSERVICEPORT 20001
  PDSRVTYPE WS^#1
  PDCLTRCVPORT 30000^#2
  
• hosts file
  128.1.1.1 hirdb01
  

#1: To operate a HiRDB server on Linux, specify PC.

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