Yeah, the single string "ip/mask" shortcut doesn't work with non-CIDR masks at
present. Use one of the alternate ways of specifying it. For example, I think
the following will work:
msg1.match.ip_dst_with_mask = ("10.0.0.4", "0.0.0.255")
.. on the other hand, this mask and IP don't actually make sense together.
You're specifying something underneath the mask...
