LiveTcpUdpWatch vs CurrPorts vs NetworkTrafficView. CurrPorts displays the current table of active TCP connections and TCP/UDP listening ports. but this technique has some disadvantages, for example, if UDP packets are sent from your computer to remote TCP/47 GRE, TCP/1723 for PPTP, TCP/1701 for L2TP and TCP-UDP/500 for ISAKMP, CISCO etc (only in case of using L2TP). that depends of the VPN tunnel type that you want to use.

This discussion about unreliability of UDP is moot. Since we're tunelling, there's UDP vs TCP (self.VPN). submitted 4 years ago by Lukeme9X. Title says it all.

I have a question about VPN technology. When we use VPN UDP completes the same job without the need of unique identifiers or sequence numbers. It sends data in a stream and only has a checksum to ensure that the data arrived uncorrupted. UDP has almost no error correction, nor does it care about lost packets. It’s more error prone, but it sends data much faster than TCP. For UDP, by default it is UDP/4500. Encapsulation to either UDP or TCP is required when the VPN traffic (by default it's ESP protocol) passes through PAT device which is normal when users are connecting from home, etc. Here is more information on default NAT-T (UDP/4500), and option to use NAT-T with TCP: Use UDP for online gaming, broadcasting, and videoconferencing.

PPP encapsulates the IP packets of data, and then transmits them to the server at the other end. PPP is an older protocol, made to OpenVPN Over TCP vs.

The screenshot below is from the NordVPN review, where I am choosing between OpenVPN TCP and UDP protocols. TCP sends out a stream of data packets while UDP packets are sent individually. Data stream doesn’t have a defined boundary but individual packets possess proper boundaries. 9. UDP is perferred for VPNs, the overhead is lower. This discussion about unreliability of UDP is moot. Since we're tunelling, there's no difference between a TCP datagram lost on the open internet and a TCP datagram lost in a TCP tunnel or a TCP datagram lost in a UDP tunnel.
