And the fix is to omit braces in definitions and use them with actual rules. For example this pf config file works: ---- smtp_ports = 25 465 pop3_ports = 110 995 email_ports = $smtp_ports $pop3_ports pass in proto tcp from any to any port { $email_ports } ---- Note that no quoting is necessary here and the parser doesn't care much about whitespace. If you run pfctl with "-v" you shall see the macro expansion which should help in understanding the parser and finding out errors. Michal
