That's working as expected. The TCP profile is just proxying the traffic
without interpreting it, so all your requests are coming from the LB.
You've got two options:
* As squid uses HTTP, you should use a HTTP profile and configure squid to
respect the X-Forwarded header as the client IP address. You may or may
not have to tweak the HTTP verbs setting depending on your usage of squid
(supporting CONNECT for non-cached HTTPS requests etc.).
* Alternatively you could use a LxNAT profile in DNAT mode which will be
able to handle more traffic, but you'll most likely need to change the
network configuration of your squid hosts (to use the lb as the default
gateway).
In later versions of ZLB the TCP profile has been removed as LxNAT in SNAT
mode gives equivalent operation (and has the same issue with backends not
seeing client addresses).
