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

heper

also note my comment that i put a dns server on the lan-side ….

i couldn't get it to work with the default dnsmasq provided by pfsense when my WAN1 went offline, this could be because i'm not capable of configuring it properly ;)

so if you are able to accomodate a dns inside the lan then you can fill in the 'Use alternate DNS-servers for the proxy-server' field in the squid configuration page.

i took some screenshots
they pretty much explain themselfs …

i currently don't have the time to write a full how-to but if you still have questions don't hesistate to ask em ;)

see below:

thanks it worked 8) 8) 8)
the detail that was picked up in nat rules to the 127.0.0.1, but everything right now and running!

I just put a patch that will include localhost(127.0.0/8) on the default nat rules so AON will not be needed anymore in the configuration.
Should be easier now by just creating a floating rule and selecting the gateway group on it.

Ermal, I have the following situation, an internal server running IIS, the rule enabled the floating leaves no service be accessed externally, is there anything to be done differently in this rule, use of nat port http to redirect traffic

This is not related to this topic or i am not understanding anything on this.
So please explain.

hi,
in floating rule, please give me the detail,

explain
thanks

nassman

i did all thing in pics, but not work

danesco

I'm trying to understand the pics, but there is many things like the direction in floating rules.

This set of rules can be used to work the wan balancing with squid? its needed the AON or not with the latest release?

igmic

I'm also trying to understand how to do this before i go and install squid. Hopefully somebody could post the steps in detail as I'm really new at this.

nassman

heper

Hello guys, i'm experiencing the same problem. I've tryed the solution you give. When i configure two links in different tiers, making failover, squid work perfectly going trough the gateway I specify. but, when I configure two gateways in the same tier, making balance, the squid can't find any site and when the user try to access any site on the internet, the browser still "searching forever" until get the "TIMEOUT" message. Did one of you experienced that too? what am I doing wrong?

Just for information:

I have two links: 1 PPPOE and 1 Static from 2 different ISPs in two different interfaces.
I have a Lan where are all the computers and a DMZ where are a Web Server that is a DNS server too.
The LAN's DNS server is the PfSense.

thanks, we need Pic's with explain, step by step.

i'll try to write up a step-by-step howto in a couple of months …. the free time i have is precious and going to the pub is more fun then writing a howto ;)

basic steps are this:

get loadbalancing/failover working without squid (search the forum)
install squid
setup rules as shown in this post
configure squid as shown in this post

as promised below u'll find the float rule detail screenshot:

Heper, I am almost there…
I found out that my problem is with the DNS. So i see that you posted something about that. You have said that it's need to have a DNS server on the LAN side, so in my case that are a dns server on a DMZ, needing to pass trough the pfsense to access, it can't be done?

Just loadbalance even DNS as well as you do for TCP traffic.

igmic

Thank you Heper!

I just put a patch that will include localhost(127.0.0/8) on the default nat rules so AON will not be needed anymore in the configuration.
Should be easier now by just creating a floating rule and selecting the gateway group on it.

Ermal, may you please expound on this. What is the difference between this and heper's screenshots? Thanks!

eri--

You have to put an additional rule the same as in the previous screenshot but the protocol should be UDP and outgoing port 53.
That will help with dns.

nassman

i will try to config it, now i dont need to add AON rule, or need
