Load Balance and Squid does not work runnig in the same server

[rubic]

Heper, thanks for your guide!
What advanced option used in the "matching rule, to stop balance twice" floating rule?
I used TCP flags: out of: SYN.
It works!

[heper]

rubic:

it's possible to 'mark' packets when they hit one of your rules. Afterwards you can "search" for them packets using other rules, sort of ;)

so basically i use a floating rule to push all http traffic through de gateway-group; at the same time i 'mark' them.

i put another floating rule IN FRONT of my loadbalance-rule and added option 'quick' ; there i push packets out without going through gateway-group ; here i specify to 'match' the packets i 'marked' in my secondary rule.

see this

Hm… will think about... however, looking at pf packet flow diagram, I wonder if floating load-balance rule can fire twice
by the way, in my case your solution works even without binding squid to loopback ???

[rubic]

heper, you were right!
when default WAN is down, an outgoing packet hits the rule twice (both on WAN fnd OPT-WAN interface)
if you don't mind I would like to translate your how-to for russian pfSense community
thanks!

It hits it twice but really it does not execute the policy routing the second time.
Only the nat rules are executed.

@ermal:

Only the nat rules are executed.

There is one moment with NAT unclear to me. According to pf packet flow diagram (http://homepage.mac.com/quension/pf/flow.png) filtering happen after SNAT. That's why in the rule log we see: if:WAN src:WAN IP -> dst:remote host IP. But when packet rerouted by the policy routing rule reaches OPT-WAN outgoing chain (assuming WAN is down) it's source address appears magically restored to 127.0.0.1. Which block on the diagram do that?

[heper]

my "how-to" can be translated in any language … it's only purpose was to return the info i got from ermal to the community ;)

rubic, its pfSense customized pf(4), by me. :)

This functionality can not be done with standard pf(4), at least the version that is used on FreeBSD, without too much tinkering.

Ok, now I see :) Thank you for your work!

Ok the guide works with FailOver, but for LoadBalance???? Thanks

[juniorghr]

Please, where I am testing the sense pf 2.0 is required to enter some sites that require https and when I configure squid with loadbalance the gateway connection changes every time, how can I fix this?

Please help.

[Frozen_Fire]

Please help…Load balancing is ok...but squid is not functioning...please do some ups in the floating rule..
Thank you...

[heper]

@juniorghr

well you could create a dedicated gateway group with failover (different tiers) and add a seperate rule  for https traffic to use that gateway group …..

or you could enable 'sticky connections' in system  .... but i don't know if that would solve all issues

[onkeldave83]

Yes, BUT WITH THIS SOLUTION YOU CANT HAVP as parent for SQUID ;)

[farrukhndm]

I Follow the same above procedure but no success,My browser just working working and working without showing any results.
my configurations are.

My browser dosn't open any page after given settings ?????..Where I have take mistake. please guide me .


[Frozen_Fire]

@ far … your Nat ountbound should be set to "manual"

[eri--]

You need only loopback interface on squid selected.
Also on LAN the rule with a GatewayPool should not match the port 80/443 tcp which get handled by squid.

Has anyone got failover working on 2.0RC3?  I have been trying to get this working for several days now and and have not been successful.
