What are the different types of VPN? – IPVanish

OpenVPN can use both the TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) communication standards. Most VPN providers let you choose between them. But, few explain the OpenVPN TCP vs UDP difference and any advantages one has over the other. The function of both standards is to split your data into small transmittable packets.

The Cisco VPN client is the client side application used to encrypt traffic from an end user's computer to the company network. IPSec is used to encrypt the traffic. When using standard IPSec, IKE is used for the key negotiation and IPSec to encrypt the data. IKE uses UDP port 500 and IPSec uses IP protocol 50, assuming ESP is used.

Our VPN service uses these ports for Firewall configuration: For OpenVPN, we allow connections via TCP or UDP on ports 443 or 1194. The IPVanish software uses port 443. Why is TCP more secure than UDP? - Information Security EDIT: UDP and TCP have specific uses, none of these uses relates to security. Both protocols rely on other protocols to provide security. So although TCP may have a slightly smaller attack surface, this is really inconsequential as to secure either you require a security orientated protocol. Protocol such as DTLS or googles QUIC.
