Both Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are protocols for sending data packets through the internet built on top of the Internet Protocol. VPN or Virtual Private Network is a connection between a network with other networks in private over the public network. or in other words to create a separate WAN actual both physically and geographically so logically form a single netwok, packet data flowing between the site and from remote access to users who do will have encryption and authentication to ensure the security, integrity and UDP is mainly used for online streaming and downloading. TCP is more reliable but a little slower than UDP and usually used for web browsing. You can watch our video for a more detailed explanation:
UDP 17771 (relay connection port). If UDP direct and relayed methods fail, it is unlikely that TCP connectivity will work. In some environments, a hardware firewall
Toutefois rien n'empêche de configurer OpenVPN pour fonctionner sur n'importe quel autre port et même utiliser le protocole TCP si nécessaire. Quels sont donc les avantages et inconvénients de chaque implémentation ? La configuration "classique" (UDP, port 1194) a l'avantage d'être un peu plus rapide du fait de l'utilisation de UDP.
TCP vs UDP over an open VPN. The differences between them explained and how to choose the best one for your needs.
Those protocols are almost all TCP-only and not UDP. On such networks it's useful to also support TCP connections, even though this is less ideal due to the possibility of the TCP Meltdown phenomenon. But given the choices between something that works reasonably well or not at all, we've chosen to be practical and also support TCP. By default we choose the port TCP 443 which is the same port PrivateVPN prend en charge de nombreux protocoles. Si vous utilisez une app VPN, configurez-la pour qu’elle sélectionne automatiquement un protocole VPN qui est le plus adapté à votre réseau. Si vous n’utilisez pas une app ou si la connexion ne convient pas, essayez les protocoles suivants dans cet ordre : OpenVPN avec UDP/TCP 4. IPSec over TCP might be necesary when the intermediary NAT or PAT device is stateful firewall. With IPSec over TCP there is no room for negotiation like there is IPSec over UDP. IPSec over TCP packets are encapsulated from the start of the tunnel establishment cycle.This feature is available only for remote access VPN not for L2L tunnel Un scanner est un programme qui balaye une plage de ports TCP ou UDP sur un ensemble de machines, afin d’établir la liste des couples machine/services ouverts. Dans le cas de TCP, il ouvre une session en émettant un SYN et attend la réponse SYN/ACK de la machine distante. Dans le cas de UDP, le scanner n’ouvre pas de session mais émet un datagramme et attend une réponse. Le scan You may see UDP and TCP related to VPN’s. What do they do, and how will it change how a VPN works. This short guide shows the difference between UDP and TCP.
SSL VPN over UDP still attempts to connect to the VPN server on port 443, but unlike HTTPS traffic that uses TCP as a transport protocol, it uses UDP. Some firewalls and proxies may flag this as suspicious and drop the traffic. It can also be seen as peer-to-peer traffic (which it actually is) and again be dropped.
Also OpenVPN is very 'Firewall friendly', means that OpenVPN's UDP packets or TCP streams usually travel without hindrance.
