Configure Port Forwarding on your Technicolor C1100T modem Port Forwarding allows you to enter ports or port ranges to forward Internet applications to a LAN device. Re: Router BGW210-700 Port Forwarding This video helped me set up access to my camera even though I have a BGW210-700 (instead of NVG589). Use ssh port forwarding to tunnel another ssh session (including all its port forwardings) through a firewall. Dynamic Port Forwarding is the third major method of port redirection with SSH. Port forwarding lets you connect to virtual machines (VMs) in an Azure virtual network by using an Azure Load Balancer public IP address and port number. For example, if you make a connection from your browser using HTTP on port 80 TCP, firewall with content inspection verifies that the traffic is actually HTTP compliant and lets him go, but if you try to push SSH or FTP traffic through port 80 TCP, it will be blocked as not compliant.
