Re: [Swan] Error with LibreSwan to Huawei VRP Connection

Nick Howitt Wed, 02 Nov 2016 01:27:07 -0700

How long is the connection running before it times out? 1h? Is there anyreason you've set rekey=no?

Hi Nick,

Great thanks for the feedback. I've removed all spaces and am seeing
the same result. I'm awaiting some logs from the remote which I'll
forward on as soon as I get it.

Regards
Ian

Hi All,

I'm having huge issues setting up an IPSec tunnel from a Libreswan

in pinpointing what the error is
