Often it is better to use a table to hold addresses:

table  { $an $bn } 

works,

Roughly speaking, in the macro it doesn't work since / cannot be part
of an unquoted string.

More syntax/parsing issues in the lists/macros of pf

Is it possible to use a macro variable with a network CIDR value and then
reference it later in a list?

E.g. This first example is fine:


a = “1.2.3.4”
b = “2.3.4.5”

c = “{“ $a $b “}”

works as expected, that is c ends up as a list with host values:

c = "{ 1.2.3.4 2.3.4.5 }”

But if one uses the CIDR network format for any one of the variables, a syntax
error is created:

an = “1.2.3.0/24”
bn = “2.3.0.0/16”

cn = “{“ $an $bn “}”

Output from pfctl -nvf /etc/pf.conf:

a = "1.2.3.4"
b = "2.3.4.5"
c = "{ 1.2.3.4 2.3.4.5 }"
an = "1.2.3.0/24"
bn = "2.3.0.0/16"
/etc/pf.conf:36: syntax error
