How to use

  1. Select the "type" of static IP - multiple or single static IP
  2. Input the IP address(es) in CIDR notation
    • The CIDR notation has 3 decimal dots and 1 slash
    • Example of an IP address in CIDR notation: 179.17.161.114/24
    • Single static IP requires just one IP address (which is actually the WAN IP). The number after the slash is likely "24" (needs confirmation)
    • Multiple static IP requires both WAN and LAN IP addresses. The number after the slash for the WAN IP is likely "24" (needs confirmation)
  3. Click on "Calculate"
  4. Profit!
