Sshuttle is a transparent proxy server over ssh that works as a simple VPN. Adversaries may communicate using the Domain Name System (DNS) application layer protocol to avoid detection/network filtering by blending in with existing DNS tunneling. By blocking suspicious DNS is a critical foundation of the Internet that makes it possible to get to websites without entering numerical IP addresses. The traffic to this port gets tunneled via DNS (because the dns2tcp client is listening on this port) to your remote server (where your dns2tcp server is waiting on port 53 for incoming Again, I should remind you that this method of tunneling can be slow by nature of how DNS works. DNS exfiltration and tunneling techniques Keylogging server and client that uses DNS tunneling/exfiltration to transmit keystrokes through firewalls. This can be used to tunnel SSH traffic through an ICMP tunnel. VPN Over DNS Tunnel : SlowDNS is free Tools app, developed by TunnelGuru. Add the following records: t1 IN NS t1ns.
