Question On OpenVPN Ports & Recommendations

b1ggjoe

Hey Everyone,

I was recently taking a look at a buddy of mine's Open VPN setup. He mentioned that for his setup, he enabled the following:

- Port tcp 443

- Port udp 53

- Port udp 1194

So from what I can tell, it appears as though Port UDP 1194 is the default port used in OpenVPN configs. Then it seems as though the other two ports are alternatives.

Has anyone seen this type of setup? Is it common to have more than one port, in case the network you are connecting from blocks you from accessing the default udp port of 1194?

I ask, especially because of the note on the top of this page that talks about tunneling over tcp.

Can anyone offer any words of wisdom in this area?

Thanks!

FYI: IANA Assign port number for OpenVPN: 1194

more or less exactly like my setup .. yes it is common to use these ports to try to get around strict-ish firewalls.
(Although even these can be blocked effectively with DPI)

Tunneling using TCP protocol is much slower performance .. as well as the points mentioned in the link in the page heading.

Gents,

In terms of alternative port configurations for OpenVPN, has anyone implemented creative server configurations to by-pass extremely restrictive firewalls? For example, has anyone implemented OpenVPN connections over Port 80 or Port 20/21, Port 25 for example?

I would love to know what you guys have done in this area.

Thank you,

J.
