I have a Netgear Prosafe firewall FVX538 v2. I have three public IP addresses. One address is assigned to WAN port 1 which has a MAC address. How do I make the other two public IP addresses visible to the Internet?

    Yes, I have and that doesn't work. I can't ping the external IP from the Internet or bring up the web page of the internal LAN server from the Internet.

    The last sentence under the section called: IP Address Requirements says; "The other addresses do not have to be contiguous, or on the same subnet, but your ISP must provide a routing path to them."

    What does that last part mean; "but your ISP must provide a routing path to them."? I've talked to my ISP and they say they don't have to do anything. But I'm not so sure, this started with we upgraded from a DSL 12Mb connection to a 20Mb fiber connection and we are coming into a different router on their end.

    "The other addresses do not have to be contiguous, or on the same subnet, but your ISP must provide a routing path to them."

    That is just a fancy way to say that your ISP must route (forward) traffic for the IP address to your router.

    I would double check your rules that allow, or disallow, traffic and make sure you have them correct.  I have not used that firewall, does it have logging?  If so you may want to enable it to see if by chance something is denying/blocking the traffic.  

    I would also verify with your ISP which link/connection they are forwarding that IP address on.

    You and I were both right. The ISP has to provide a forwarding path. In the last half-hour, they finally did that on one of their edge switches and that fixed the problem.
