Issue with routing traffic through a server.
Issue with routing traffic through a server.
You're facing a common issue where the connection works for a short time but then drops. It sounds like you're trying to manually configure a port, but it's not behaving as expected. Setting up a Dynamic DNS might be helpful, especially since your server has a static IP. Don't forget to share the screenshots for reference.
Did you restart your router after setting up those port forwards? I'm having some strange problems with port forwarding on my Netgear R7500. Also, have you considered using the same port for both LAN and WAN instead of mixing them up?
That's the issue. Your friend's setup uses a Comcast modem/router, but it doesn't allow port forwarding. You might need to reach out to your ISP to check if they can assist with this. Since they have direct access to the device and its settings, they can resolve the problem.
They do have access to all configurations. Some providers restrict users from modifying certain aspects to prevent issues. Additionally, not all settings are visible—some are concealed. This is why I avoid using ISP-provided units; I favor purchasing my own, since they not only control the settings but also have visibility into every connected device.
This Telus modem offers many capabilities and supports seamless port forwarding. I've been hosting several servers from my home for the last eight years.
He’s been relying on a Comcast modem for years, but it doesn’t forward anything useful. This isn’t just his problem—I’ve seen others face the same issue. Plus, Comcast is known for sending faulty equipment back into service. That’s why I avoid using a Comcast modem myself; I’m not paying $10 a month for unreliable gear.
