Force source port (client)- STUN

Post by pparent » Thu Apr 26, 2018 10:32 am

Hi,

In order to establish a connection via STUN, we need to be able to ask openvpn to use a specific source port on client mode. For example we need to be able to ask to connect in UDP to 1.1.1.1:35000 with source port 36000.

By default openvpn uses random source ports. Is it possible to have control over source port used by openvpn?

Thank's a lot in advance!
Pierre.

See --lport in the manual.

Sorry for once again asking for a trivial question.
