Yes, but one writes this in CIDR style, thus for your example: block out quick on $external from any to 123.123.100.0/24 block out quick on $external from any to 123.123.200.0/24 A /23 would be 100 - 254, see 'sipcalc' or other such tools for calculations. Also see Wikipedia's CIDR entry for more details. Greets, Jeroen [demime 1.01d removed an attachment of type application/pgp-signature which had a name of signature.asc]
