the last interface that i have, use pppoe to connect with adsl to internet.
my subnet mask that set on that interface is 255.255.255.255 but when i trace change route in squid inc, i found that ifaces variables are these:
Array ( [0] => Array ( [0] => 192.168.110.5 [1] => 255.255.255.0 ) [1] => Array ( [0] => 127.0.0.1 [1] => 255.0.0.0 ) [2] => Array ( [0] => x.x.x.x [1] => 0.133.150.130 ) )and this is the result of localnet in squid.conf
acl localnet src 192.168.110.0/24 127.0.0.0/8 0.1.16.128/0.0029437763168723
