BGW320 and multiple public IP addresses
I know this has been asked and answered many times, but many conflicting answers exist. Here is the scenario I'm trying to impliment if anyone wants to comment.
My environment:
BGW320 Gateway Router
/29 static IP addresses
What I want to do is have each public IP address go to a different router or server.
Example assume I had the block nnn.91.12.168/29
Router 1: nnn.91.12.169 -- Office network router [DHCP for 192.168.2.0 network]
Router 2: nnn.91.12.170 -- IOT network router [DHCP for 192.168.30.0 network]
Server 1: nnn.91.12.171 -- public file server
Router 3: 99.91.12.174 -- Test network router [DHCP for 192.168.12.0 network]
BGW350 configuration
Public Subnet Mode: On
Allow Inbound Traffic: On
Public Gateway Address: nn.91.12.168
Public Subnet Mask: 255.255.255.248
DHCPv4 Start Address: nnn.91.12.169
DHCPv4 End Address: nnn.91.12.174
No Cascaded Router
Hard code public IP addresses for the routers and server.

With the exception that the DHCPv4 end address should be nnn.91.12.173 instead of .174, and Router 3 should use .173 instead of 174, it looks good to me. The Gateway will claim nnn.91.12.174 on the LAN, and that is what you should use for each router/server's Default Gateway IP.

The part that was not clear from the various on-line forums is that the only thing that needs to be done is to statically assign the router, server or whatever device is going on the public internet IP address. Just make sure the addresses are correct.
JefferMC, thanks for the heads up about the gateway claiming the high address, that would have caused me a headache. One trick I have is to assign one of my devices at the highest address as a reminder where it ends.
