I have setup squid to use a single ingress (http_port) IP address on the /24, and set the egress (tcp_outgoing_address) IPs via ACL to randomly select an outbound IP from the entire range of assignments. Unfortunately, squid will only send traffic out the /24 or the primary IP of the box. I have tried setting ingresses on the other /29s and sending traffic through them, but squid persists in sending all traffic through the /24 or primary IP regardless. I have seen many others with this same issue, but no solutions that use a single squid instance without child proxies. Suggestions would be appreciated. My excerpted configuration is here: https://privatepaste.com/621ade44d6 What is the default gateway of this box ? The outgoing traffic (which is not meant for any of the connected networks) will always leave through the interface connected to the default gateway. In case you want to have multiple outgoing addresses belonging to the same subnet on an interface, you just have to ensure that the default gateway belongs to that subnet so that the traffic always leaves through it. For example if you have a subnet a.b.c.0/29 where a.b.c.1 is the gateway, you can assign the following IPs to the external interface of the system (and use the same in ACLs for tcp_outgoing_address): a.b.c.2 a.b.c.3 a.b.c.4 a.b.c.5 a.b.c.6 and specify a.b.c.1 as the default gateway of the system. However, if you have IP addresses belonging to different subnets (a.b.c.0/29 and a.b.d.0/29), you will have multiple gateways and you will have to configure routing accordingly.
