'PTunnel' reliably tunnels TCP connections over ICMP echo request and reply packets (aka ping requests and replies). It evades firewalls that prevent outgoing TCP connections, but allow in- and outgoing ICMP packets. The tunnel works by having a proxy run on a machine ping-able from the inside of the firewall; the client runs on the local machine from which TCP access is required.
