SSH: Tunnelling arbitrary remote hosts

ssh -L local_port:remote_target_ip:remote_target_port ssh_server_ip

for example:
ssh -L 23000:
once authenticated against, encrypted connectivity to the telnet server running at is possible just connecting to

(lsof -i -n would confirm there is a new port listening on localhost:23000)

here is a nicely illustrated quick note for bypassing firewall (inbound) policies.
