We have a client with a Balance 580 with PepVPN/SpeedFusion being managed by InControl. We need to connect them to another client running a Max BR1. We’ve done this via IPSec before without issue but on this install we keep getting “Malformed payload, please verify the Preshared Key or other settings.” We’ve check the preshared key countless times, deleted everything and started from scratch, compared it to another Balance 580 to BR1 IPSec tunnel and just can’t see what’s wrong. The only thing different with this Balance 580 is that it is setup as High Availability but not sure why that would matter. The BR1 just logs “Initiating Main Mode connection to…” but the Balance gives the 'Malformed payload" error.
The Balance 580 is firmware 7.0.0 build 1904 and the BR1 is 7.0.0 build 2445. I’ve done this several times so I’m at a complete loss on this one. Thanks for any help.
