Network tunneling and port forwarding take advantage of firewall "pinholes" (ports not protected by the firewall that allow an application access to a service on a host in the network protected by the firewall) to establish a connection with a remote server blocked by a firewall. including the default RDP port TCP 3389. This type of RDP

How to Create SSH Tunneling or Port Forwarding in Linux Sep 26, 2018 What Is DNS Tunneling? - Palo Alto Networks DNS tunneling is one such attack. How DNS Tunneling Works. DNS tunneling exploits the DNS protocol to tunnel malware and other data through a client-server model. The attacker registers a domain, such as badsite.com. The domain’s name server points to the attacker’s server, where a tunneling malware program is installed. Understanding TCP over TCP: effects of TCP tunneling on

SSH port forwarding - Example, command, server config

Aug 03, 2006 When is it appropriate to use UDP instead of TCP? If you tunnel TCP over TCP, the congestion controls of each will interfere with each other. Hence one generally prefers to tunnel TCP over UDP (or some other stateless protocol). See TechRepublic article: Understanding TCP Over TCP: Effects of TCP Tunneling on End-to-End Throughput and Latency.

The TCP tunneling has even better quality, but it doesn’t tolerate too much packet loss so good than UDP does. The HTTP tunneling has between 5% and 35% overhead and needs more server side resources (but it is needed only from behind corporate firewalls when the only single route is via the local http proxy).

SSH port forwarding is a mechanism in SSH for tunneling application ports from the client machine to the server machine, or vice versa. It can be used for adding encryption to legacy applications, This allows anyone on the remote server to connect to TCP port 8080 on the remote server. Firewall - AnyDesk Help Center
