SSH tunneling: encrypted conduit through firewalls

SSH is not just a remote shell — it's a general-purpose encrypted tunnel. Any TCP traffic can be forwarded through an SSH connection, effectively bypassing firewall rules that block direct access.

Three forwarding modes: local (reach a remote service as if it were local), remote (expose a local service to remote access), and dynamic (full SOCKS5 proxy for arbitrary destinations). Together they cover most secure access scenarios.
