UDP or TCP

Gil · May 26, 2018, 7:42 AM

I run a number of OpenVPN services for a variety of clients.
Most of them are for streaming, so I use TCP.
I have one OVPN server for FTP which I have also run on TCP, but I am re-thinking that it could perform better on UDP.
Any thoughts?

Almost everything will run better over UDP.

A good read, thanks Derelict

Some people (including myself) are using both for various reasons.
Having a server listening on 443/TCP may help to bypass firewalls.

That may be but for performance reasons it will suffer but might be better than it not working at all.

@derelict said in UDP or TCP:

might be better than it not working at all.

Might be? hehehe you could say that... Kind of hard to bounce a vpn connection off a proxy with UDP.. And 1194 not always open - but pretty much given that if there is internet access 443 tcp is going to be.

The OP asked about performing better. And that is the answer that was given. Needing to use TCP for other reasons is pretty much off-topic.
