Does anyone know why I can no longer use Port 22 for SSH connections from the internet? I can no longer set up the port forward rule on the relevant page on 192.168.1.1 - I used to be able to do it no problem, but now I get told it is "reserved for internal use"
I spoke to someone in tech support earlier and they weren't sure what I was talking about. Any clarification on this is greatly appreciated as I can no longer do my job when I'm out of the house so I'm looking into changing suppliers.
You are not the first person to report this and I doubt anyone will get a definitive answer on the subject. The two most likely options are that there is indeed a conflict with an existing service built into the router, or that as a consumer router VF thinks that allowing SSH on port 22 poses a potential security risk.
You should, however, be able to port forward from another external port to port 22 on the device that you are trying to connect to.
Thanks for your response. I wish there was a way to allow this, as I can limit access to my internet facing device over ssh to my phone's mac address (i.e someone would have to physically nick my phone and then guess my ssh password to get in). I've tried routing ssh traffic through port 2222 both on the router and the internet facing device with no luck - its like Vodafone are just blanket disallowing ssh connections from the public internet. So frustrating that I have to go through the chew on of changing suppliers and re-configuring another router all because they wont allow me to connect!
Alternative is to set up a VPN within your LAN (where you want to SSH to) that you can connect to from the WAN. When you connect to the VPN, you can SSH to the local device from the WAN. (Probably a more secure way than opening port 22 to the WAN).
I will investigate this, thanks! My issue is my work network is IP locked (im a DevOps Engineer) and I've actually triggered a security alert trying to connect to it directly from a 4G phone connection, so I'm not sure if connecting over a VPN might trigger the alert too, especially in an emergency situation when I cannot add the VPN to an allow list.
Sorry my bad there, I'm used to normal systems where it's possible to say route TCP port 1234 on the web IP to port 22 on a device within the network. Vodafone doesn't block SSH, but their router is certainly a strange beast!
I can connect to anything I need to except for SSH to devices on network. I’ve changed the port so doesn’t use port 22 but still cannot log on on voxi network, but using WiFi hotspot at my employers premises works fine.
so somehow it seems there is a block on ssh connections on voxi
If you weren't connecting through OpenVPN then I say it was probably CG-NAT on the Voxi connection causing the problem. But the tunnel should mean it will work.
