Several public IP addresses available simultaneously.
Hi there! You're using a Zyxel VMG3925-B10B, looking for additional public IP addresses. Since there aren't many recent guides, you might try searching forums or checking the official Zyxel documentation for setup tips. Good luck!
Having multiple public IP addresses involves two options: a router supporting multiple IPs with capabilities such as 1-to-1 NAT and port forwarding, or using a setup with a switch and multiple routers. The device you currently have likely lacks these advanced features since it's meant for everyday use. Consider placing a switch between the router and the modem, or using a router that includes bridge mode to act as a modem. For clarity, the IP addresses your ISP provides can be simplified by removing the middle digits, like 206.x.x.145
Emphasizing the need to eliminate the central sections of your IP when sharing, as highlighted by Brwainer.
Halt. Avoid distributing this information. Even without the specified triplet, refrain from sharing unless necessary for public devices. Obtaining several public IPs from one router typically depends on your ISP providing at least a static IP and a DHCP address. 1:1 NAT or multiple WAN addresses are alternative options, but they also require an ISP that supports them.
The concepts of 1:1 NAT and port forwarding aren't directly related here. NAT and PAT serve different purposes, which is why they exist separately. Also, requesting his IP address isn't necessary unless you're seeking multiple IPs, in which case you'd need to contact your ISP for a block like /29. It won't be free, and they won't provide just two IPs or static addresses with DHCP. They only offer exceptions for business accounts. If you're willing to pay, consider a more advanced router such as Mikrotik or an older Cisco ASA model. These allow assigning multiple IPs to one interface and using zones for NAT and other devices.
You can combine 1:1 NAT and port forwarding effectively. My setup uses five IP addresses on a Mikrotik router. I open ports for VPN, redirect others for services, and use two IPs with 1:1 NAT while the remaining two handle traffic via NAT. This configuration is straightforward on Mikrotik (or similar Linux firewalls) by arranging the rules correctly. It would be more complex on platforms like WatchGuard or Fortinet. I’m curious if you have additional IPs—like .187, .188, etc.—or if these are all your addresses. My goal is to clarify so I can assist you better.
