RE: kern/185876: ipfw not matching incoming packets decapsulating

Hey,

First off all, thanks for the patch, should we wait for FreeBSD 10.1, use 10.0/stable or patch it our selves?

Or is this going to be issued as Errata patch for FreeBSD 10.0-Release? (which I think it should be)

Kind Regards,
Robert Sevat
