Still couldn't get it to work.. failover works great if I don't have Squid running.

We need LoadBalancing and FailOVER! squid guys working faster please!

@DimitriS
Did you tested this setup in case of loadbalancing?
After my test it perfectly works in case of failover, but not when I set up loadbalancing between two gateways..
I tried to bind squid to loopback and LAN and only loopback, and works well only when gateways sets in failover.

I agree with mbedyn, failover works but not loadbalancing.

Saw the same thing here. Fail-over yes, load balancing no.

same here no loadbalance only failover. Also the redirect error page in squidguard doesn't point to the redirect page.

Good Job

Hello.
For three days I'm trying to do this.
I tried and tried, but I can not get it to work.
I can not open web pages it opens and then stops and does not go more 'forward.
I attach a screenshot
As you can see I can not even do program updates.
If anyone can help me, I would do a big favor.
Thanks to all.

@zetar

what does not work ?

are you able to do basic loadbalancing without squid ?
if no -> read the sticky about loadbalancing / failover in 2.0 forum

if yes -> is your floating rule being hit when trying to access a page ? –> if yes then you could be having a dns issue, duplicate the floating rule you have for http but change to tcp/udp and destination to DNS (53)

Hello.
Thank you for reply.
I reinstalled from the beginning.
The load balancing has worked very well until the installation of the Squid.
After the Squid and the fact the rules as you said to no longer works.
Attached is a screenshot of the rules are created by me for other services.
Can interfere at times.
Another thing, what are the correct values to put as the threshold latency and packet loss.
After the rule of floating, I found this rule, that fact alone, can 'interfere. Screenshots.
Another problem by loading a download of 6 7 megs no longer opens the page. I have to stop the download.
Thanks again.

If you notice the OPT1 and 'upload. the other three WAN server always does not happen.

Will these work for 3 ISP or 3 WAN links?

kirlox_kitoy

have you tried not to append the custom options which is the loopback maybe that will work.

@heper, I had setup squid load balancing following your instruction and it works (kind of). I fell unstable / slow performance while serving the web. Like I open a website the website may load halfway then it kept loading but nothing display. I need to refresh it then only it load the entire page. Or sometime it may never load the page at all but it never say "page cannot be display" etc, it just kept loading.

Also it cause my Online Games not able to connect to it server. The NAT outbound setting would it cause any trouble to go for manual? May it be the reason why my Online Games can't locate the server?

If I specify the proxy in the client it works well.
