Cisco Tunneling Control Protocol
Cisco Tunneling Control Protocol (cTCP) enables VPN clients to operate in
environments where standard ESP protocol (port 50) or IKE protocol (UDP port
500) are not permitted. For a variety of reasons, firewalls may not permit ESP or
IKE traffic, thus blocking VPN communication. cTCP solves this problem by
encapsulating ESP and IKE traffic in the TCP header so tha t firewalls do not see it.
