Squid with multi wan doesnt work as intended

[xbipin]

thanks for the link but i have read those old configs before also but my setup is different, i dont want to use my multi wan as load balancer or fail over, i want to route specifically based on originating ip and if u see my rules, it works fine without squid but with squid, traffic goes out of the wrong interface

Hmm, thought, that a combination of having Squid use 127.0.0.1 as outgoing address and a well crafted floating rule with gateway wan2 might work.

[xbipin]

in squid i typed this

tcp_outgoing_address 127.0.0.1;

on floating tab i created a rule

pass
quick disabled
interface wan1 and wan2
direction out
protocol tcp
source and destination any
source port any
destination port 80
gateway wan2

and i logged packet also and it seems it still goes out of wan1 instead of wan2

Does the rule get any hits, do you see log entries for it? Otherwise there might be interference with pfSense internal rules, I guess.

[xbipin]

yes the floating rule gets hits but interface is always shown as wan1 inspite of me routing out of wan2 using the rule so probably it has some bug i guess unless there is something else to be configured.

i use whatsmyip etc to check the ip and all say traffic is coming from wan1 instead of wan2

Tried to replicate it, but I am getting the same results you get. Seems there's something more involved. When I use Quick for the rule, the traffic hits the ruleset twice and it dows not work at all. But I cannot debug this further now, sorry. I'm not at home and might lock myself out playing with the ruleset too much ;)
I remember there was something about negate rules, but I am not sure if that applies to this problem.

Edit: The "Squid-way" to solve this would simply be

tcp_outgoing_address <wan2 ip="" address="">;</wan2>

Don't know how complicated it would be to make the outgoing address an option in the Squid package, though.

provided the wan ip never changed

[athurdent]

Like I said, an option in the package would be needed for that.

just put it(tcp_outgoing_address <wan2 ip="" address="">;) on custom_options.

You will need to update it every time you get a new wan address if you do not have a static wan.</wan2>

[xbipin]

thats the whole thing, i dont have a static ip so why not use some coding to feed in ip when it changes to it, mayb a drop down similar to gateway which can be selected and it changes with ip change
