Why is this blocking ALL activity?

[Robert Chalmers]

I can't get the List: syntax to work...


RC> This works,
RC>         ${fwcmd} add deny log all from any to 203.1.96.1 in via ${oif}

but this doesn't
${fwcmd} add deny log all from any to 203.1.96.0/24{6-25,27-154,156-199,204-254} in via ${oif}

Can someone tell my what I'm doing wrong please ?
I'm trying to block any sort of access to a range of internal IP addresses.

RC>              As an example, an address specified as 1.2.3.4/24{128,35-55,89}
RC>              will match the following IP addresses:
RC>              1.2.3.128, 1.2.3.35 to 1.2.3.55, 1.2.3.89 .

Thanks
Robert
