Try this small test case to see my problem: #define addr 192.186.2.5 #define mask 255.255.240.0 #define rule(ADDR,MASK) add pass tcp from ADDR ## : ## MASK to any 25 setup rule(addr,mask) This also does not work if addr and mask are defined on the command line. The problem arises from using another defined value as the string being concatenated. The concatenation works for constants though.
