PfSync to 'offline' server



  • Wasn't sure how to word the subject…

    I have a pfSense 'Edge' router.  I have one public IP for that edge router.  I have two servers; one is in production and one is currently powered off.  I would like to power on the server and sync the production config over to 'backup'.

    To minimize down time, I wanted to have a 'warm stand-by' up and running so worst case I swap cables if the hardware dies or has a problem.

    Since the 'WAN' and 'LAN' interfaces will literally be unplugged, is there any reason why pfSync wouldn't work?

    Thanks ahead of time for any assistance.

    pfsync would be state sync, which wouldn't would want/need in a cold spare.

    For config sync, XMLRPC might be helpful but honestly for a cold spare like that just take periodic backups of the primary and restore them in-full to the cold spare. XMLRPC sync would add a lot of complexity for very little net benefit in that case.



  • Understood!  Thank you for your in-site and your time!
