1U modem and router in one compact unit.
1U modem and router in one compact unit.
We're simplifying our home network setup (aiming for an ISP-ready configuration for labs and certifications) and want to tidy things up. We're facing two challenges and welcome any ideas, even the most unconventional. * 1U Comcast compatible cable modem: no wireless, no NAT, no port redirection—just a coax connection on one side and an RJ45 on the other. If we need a unit that fits into a 2U space, a shell can work too, or we might need to redesign it entirely. We're after something straightforward, not extra features, just a bridge between their network and ours. * 1U Router: searching for a basic, configurable router sized for a 1U enclosure, ideally with simple iptables and port redirection capabilities. It should handle blacklisting, whitelisting, and routing basics. We're used to NAT setups from the past—reminds me of using a Sparc 20 with dual network cards. What works on our side matters most; we just need to connect to the real world for streaming services like Netflix. Bonus: we’re open to creative solutions. I’m not sure if there are rack-mountable Comcast modems, but maybe a simple 1U router exists. Old Dell 1U servers with two NICs and decent CPUs could handle 100Mbps routing? Also, no wireless devices—WAPs don’t fit the bill. Thanks!
The rare rackmount DOCSIS 3.0 modems are hard to find in regular stores; they’re usually leased from the cable provider. A typical approach is to use a compact modem, about 1U thick, and mount it on a shelf. Motorola Surfboard models are popular and don’t distinguish between consumer and business versions. For routers, there are many basic units built for PFSense or OPNSense that work with any operating system. You can explore options at https://www.amazon.com/gp/search/?rh=i%3...1538618732 or simply purchase a 1U chassis and fit any old motherboard inside. It’s better to choose one that comes with a PSU, since 1U power supplies can be tougher to source, and you may need a matching heatsink and a suitable PCIe bracket if extra ports are required. I favor SuperMicro and Norco for their rackmount designs.
What certifications are you targeting? I’d simply purchase any vendor model capable of handling that traffic volume—perhaps a 2911 or a budget ASA from Cisco. You could also set up a live lab setup. For cable modems, just place a standard 3.1 modem on top of the router while it’s mounted or use a shelf. There are some ehwic-style modems that fit into the router, but they’re pricier than what would be practical.
