Hello, I have a wrvs4400N. I know it's old, but I got it free. Now I'd like to be able to have the local network under a 255.255.252.0 subnet mask, however the webgui won't allow it. But I do know that there's nothing in the firmware that would actually have a problem with that subnet mask, it's basically linux under the hood. So I'm wondering if there's a way I can force that subnet mask through the gui or manually apply it through an ssh, telnet, or serial console. I have no problem cracking the case and soldering some wires to the headers, but I have no idea what commands I'd need to use to change the subnet mask and have it survive a reboot.
