As shown in Figure 25-11, a firewall and NAT have been installed on the HiRDB/Parallel Server side, and they have been configured as follows:

Firewall settings

• Direction: Receive
• IP addresses: 172.16.0.10, 172.16.0.20
• Port numbers: 20000, 20001

NAT address translation

128.1.1.1 172.16.0.10

128.1.1.2 172.16.0.20

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.

Figure 25-11 Network configuration example with a firewall and NAT installed on the HiRDB/Parallel Server side

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
  pdunit -x hirdb02 -u unt2
  pdstart -t MGR -u unt1
  pdstart -t FES -s fes -u unt2
  

Client machine settings

• Client environment definition
  PDHOST hirdb01
  PDNAMEPORT 20000
  PDSERVICEGRP fes
  PDSERVICEPORT 20001
  PDFESHOST hirdb02
  PDSRVTYPE WS¹
  PDCLTRCVPORT 30000²
  
• hosts file
  128.1.1.1 hirdb01
  128.1.1.2 hirdb02
  

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

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