      I have read pfsense book and search on this forum but no one use the same IP address that I used.
      In the pfsense book use IP address for:

      Site A              
      pfSense Lan IP: 192.168.1.1
      Lan Network:    192.168.1.0/24
      OpenVPN :        172.31.55.1

      OpenVPN tunnel pool: 172.31.55.0/30

      Site B
      pfSense Lan IP: 10.0.10.1
      Local network:  10.0.10.0/24
      OpenVPN:         172.31.55.2

      I don't want to use the same IP address as the pfsense book.

      I have a little bit confused about setup OpenVPN Site to Site IP address and CIDR route summarization.
      I have already done with Site 1 Server ( Mobile to Site ) and I still want to use the same IP address 172.31.21.1 for Server Site
      Now I want to setup OpenVPN Site to Site and I have a little bit complicated about Client Site IP address.

      Can anyone suggestion ?
      I really want to know. Is it correct or I have to change something from my network diagram ?
      Is this IP address overlap?

      My network diagram.

      CIDR Route summarization
      172.31.20.0/22 spit into /24 network

      172.31.20.0/24
      172.31.21.0/24
      172.31.22.0/24
      172.31.23.0/24

      Site1 Server
      pfSense Lan IP: 172.31.21.1
      Lan Network:    172.31.21.0/24
      OpenVPN :        172.31.23.1

      OpenVPN tunnel pool: 172.31.23.0/30

      Site2 Client
      pfSense Lan IP: 172.31.22.1
      Local network:  172.31.22.0/24
      OpenVPN:         172.31.23.2
