The answer is "probably not."  If your network looks like this:

    .-----.    .---------.
    | You |----| Linksys |---- The Internet
    `-----'    `---------'

and the Linksys is configured for NAT then it's probably blocking any
bad inbound traffic before the SuSE firewall sees it.  The option
between "on" and "off" would be "on, but with the UPnP port opened
manually."
