Warning: Enabling OS X firewall disables Retrospect Client - Mac Applications & Software

    Default Warning: Enabling OS X firewall disables Retrospect Client

    I use Retrospect Pro. Yesterday the client on my iBook kindly warned
    me that there'd been no backup for a week.

    Everything seemed fine, but the server software (on Windows)
    definitely couldn't see the Mac client.

    Then I dimly remembered enabling OS X Personal Firewall (Sharing
    preferences) prior to connecting via an open 802.11b hot spot. Sure
    enough, turning off personal firewall restored Retrospect
    functionality. Obvious in retrospect.

    Posted here for two reasons:

    1. To warn other Retrospect users. Non-experts won't think about their
    Retrospect client when they decide to enable the firewall
    functionality.
    2. To point out how darned complex our software environments are, and
    how they can break in such novel ways.

    Didn't opening up port 497 on the client Mac do any good? It works just
    fine here for Mac-to-Mac backups with the firewall enabled.
