New Host Firewall - Problems

Did anybody already play around with the new on-host firewall released with 9.5? I for the life of mine, cannot get this to work. Behavior seems worse than erratic to me.

Guesses so far:

ipfw rule writes seem to not honour subnet/pool network segment size and always default back to /24 size. Multiple ipfw table entries are generated for "same" rule...

Somebody have the firewall up and running with expected results?

    Hello CendresMetaux,

    Have you configured your firewall as stated on page 413 of the web administration guide.

    I opened an SR and had Dell support/engineering looking over it. As config seems OK but behaviour quite odd, they start a repro in the labs.

    I'll post here when more info is available...

    Well, turns out there's an open known issue/bug with regards to this:

    Firewall: ipfw rule for "allow ip from any to any in" will be matched prior to the "ip from any to any in recv" rules for additional VLAN interfaces - PSCALE-176813

    According to support it looks as if this issue will be resolved in 9.5.0.4
