[squid-users] outgoing address for DNS queries per instance

[--Ahmad--]

Hello folks 
i have 3 squid instances and i want to have different external ip for each squid instance .

i believed acls of dst ip of dns should work .
but i even tested it didnt with the outgoing address .

dns_nameservers 8.8.8.8
acl next dst 8.8.8.8
tcp_outgoing_address 100.100.100.100 next


but the problem when i do debug , the src ip that reach 8.8.8.8 is no 100.100.100.100 and its only the ip address of the main machine .

any help ?

Thanks
