[aminbaik]

Hello,
I have three wan on pfsense , and three networks , the default wan for pfsense is wan 1
lan1 wan traffic to wan 1 through the rules
lan2 wan traffic to wan 2 through the rules
lan3 wan traffic to wan 2 through the rules
I have enable squid proxy on lan 2 and lan 3
when I enable it all request that is going via proxy is going through wan1
how I can make lan 2 proxy going through wan 2
and lan 3 proxy going through wna 2 ?
thanks.

I don't think you can. IIRC, squid's behaviour is to use the default gateway.
