help with acl src and par or impar ip (odd number or even number i think.).

[Soporte Técnico <soporte@xxxxxxxxxxxxxxx>]

I have 2 two parents for my main squid (Freebsd).

I want to load balancing to each one parent the par ip (odd) and the impar
ip (even).

Ex.
acl pares src 192.168.0.10, 192.168.0.12, 192.168.0.14, 192.168.0.16 ?
192.168.0.254

acl impares src 192.168.0.11, 192.168.0.13, 192.168.0.15, 192.168.0.17 ..
192.168.0.253



May I have 2 files ?
Pares.txt with this 
192.168.0.10
192.168.0.12
192.168.0.14
?
192.168.0.254



Impares.txt with this
192.168.0.11
192.168.0.13
192.168.0.15
?
192.168.0.253



This would work ?
The speed there´s not going to be slow in because this large acl files?

There´s another way to do this more intelligent.

Thanks for the help.

Jorge.
