Squid, Multiwan, Firewall Rules Problem

[geniusphp]

Hello

pfsense build is as follows:

WAN1 (default)
wan2
wan3
Lan
squid
load balance

Everything is operating normally. However, in spite of 192.168.1.10 not to manipulate wan3 the user to create a rule, is departing from wan2 BSA from WAN1. Continuous wan2 not come from.

there is no problem when I disable squid. I always come from wan3. Once that happens, I wrote the Squid is working according to the head of the rule does not work.

How do I want to open a conduit for the output you want to ipyi squid?
