Hello, this may be a easy question, we got fiber dropped off the other day, they told us that we need one router as our gateway 25.222.15.146/29, our main router has a ip of 25.222.15.121/29 and a server with 25.222.15.122/29. what is the best way to set up up the gateway router just pass to 121 and 122? the gateway router will just be used for that only!
You can change your main router ip addres to use the gateway ip which is 25.222.15.146/29, and point everything else including your server to ip that ip address as a gateway.
