ANSWERED Custom TLS re-keying intervals in OPVN client

Recommended Posts

I'd like to refine the re-keying using OpenVPN manual configurations; what are the custom directives necessary to accomplish this? Can frequent re-keying break or interfere with downloads/uploads?

Hello!

 

Check the directive:

reneg-sec n

 

where n is in seconds

 

in the OpenVPN manual: https://community.openvpn.net/openvpn/wiki/Openvpn24ManPage

 

OpenVPN uses the previous key as long as the new key is not fully re-negotiated. Such "smart overlapping time window" ensures no communications break. Just make sure to not set extremely low values, because a re-keying adds anyway a moderate overhead in bytes, in computation power and you probably don't want that your side is willing to ask for a re-keying immediately after the previous one is over.

 

Kind regards

Thank you staff! Awesome advice. And if we are to apply this in Eddie, under Eddie settings, I'm assuming we simply use "custom directives" with the same inputs? Thanks.

"Hello!

We would recommend that you set reneg-sec time at least to 600 seconds (10 minutes). It should be enough even for the most paranoid vision.

Kind regards
