We use Opengear serial console devices. T-Mobile has the best pricing for static IP for our area. ~$15/month unlimited data. Your coverage may vary 😊 There are also some cellular router devices from the providers that have an inside LAN port that you could connect to your router(s) if that is sufficient, rather than using serial console. thanks, -Randy -- Randy Carpenter Vice President - IT Services First Network Group, Inc. 800-578-6381, Opt. 1 http://www.network1.net From: Jonathan Kalbfeld via NANOG <nanog@lists.nanog.org> Date: Wednesday, September 24, 2025 at 19:16 To: nanog <nanog@lists.nanog.org> Cc: Jonathan Kalbfeld <jonathan@thoughtwave.com> Subject: Best recommendation for out of band router access? Hello, Obviously dial up is no longer practical for most applications. I have a some of my gear co-located in a facility in downtown Los Angeles where the idea of paying a monthly for a cross connect to get a phone line is just not practical. Can anyone recommend an idea that's not super cost prohibitive that would involve some kind of 4G or 5G Sim with a static IP address that is not CGNAT? I'm running OpenBSD for my Edge routers, so plugging in a USB is not guaranteed, so is there a product that might have some kind of a bridge functionality where it will establish a mobile IP connection and then plug into my switch? Also open to reasonably priced provider recommendations. I don't need a lot of bandwidth since this would mostly just be SSH or maybe openvpn traffic. If you know of service providers as well as recommended products, that would be ideal. I don't want to spend thousands, but a few hundred dollars on gear seems reasonable.
