setting order of reply

[Andris Kalnozols]

Try this:

acl "subnet-1" { 10.0.1/24; };
acl "subnet-2" { 10.0.2/24; };
acl "subnet-3" { 10.0.3/24; };

options {
	 ...

    sortlist {
            { { localhost;          # IF   from the local host
                localnets; };       # OR   from a locally-connected net
                  localnets; };     # THEN prefer locally-connected address
            { subnet-1;             # IF   from subnet 1
                subnet-1; };        # THEN prefer subnet 1 address
            { subnet-2;             # IF   from subnet 2
                subnet-2; };        # THEN prefer subnet 2 address
            { subnet-3;             # IF   from subnet 3
                subnet-3; };        # THEN prefer subnet 3 address
    };
