Firewall Evasion and Remote Access with OpenSSH
summary
OpenSSH demos show concrete, repeatable techniques: dynamic port forwarding (SOCKS proxy) to make outbound traffic appear from a cloud jump box, local and reverse port forwarding to tunnel arbitrary TCP (HTTP, VNC, RDP) through port 22, ProxyJump (-J) and .ssh alias plumbing for multi‑hop access, and a simple ssh VPN using -w that moves IP traffic. The only daemon change demonstrated is enabling sshd PermitTunnel=yes; expect a few commands, file edits, and a surprising ability to get full network access that requires firewall/sshd hardening.
