New HOWTO: pfSense Squid Web Proxy with multi-WAN links (it works!)
-
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.

what does not work ?
are you able to do basic loadbalancing without squid ?
if no -> read the sticky about loadbalancing / failover in 2.0 forumif 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?
-
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?

Hi, i tried this and works but with low performance.
now i updated pfsense and i got this when accessing via transparet proxy

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

hello masters,
i setup failover and loadbalancing, i believe its working but not when i install squid proxy. failover is no longer working once i unplugged either of the wan connection. i cannot browse the web although i can ping 8.8.8.8, when i uncheck "allow users on this interface" i can browse the net. is there a workaround on setting up load balancing, failover and squid? i need your advise masters, thanks in advance!

Hi.
Any news about this issue ?
My pfsense 2.0 RELEASE + Squid + Failover + squidguard + Transparent Proxy still not work.
Thanks in advance.

After manually adding my subnet in the "Allowed subnets" box, my dual wan, squid and
squidguardsetup is now functioning using pfSense Version 2.0-Release (i386)UPDATE: squidguard doesn't work but squid is OK
-
Hi, first of all I apologize for my bad english…
PfSense 2.0 Release + Squid (transparent proxy) + Squidguard + Load Balancer doesn't work, only works failover, but not balancing. Without Squid, load balancer works fine.
If I do the NAT and the floating rule, without any change more, it seems to navigate and sometimes I can see the load balancer working, but a lot of times when browse it seems to stay "connected to..." and the web doesn't load fully.
I've tested with the previous configurations in "how to" (NAT, floating rule, LAN-loopback in proxy server with tcp_outgoing_address...) and the results are the same...doesn't work fine.
-
Hi,
I have realized of testing throw http://pfsense.org/ip.php to verify load balancing that when I access to this url, I see my public IP of wan1, then I refresh and I see the public IP of wan2, I refresh another time and I see public IP of wan1, then if I refresh another time and the browser keep "Waiting to pfsense.org…", I refresh and I see my public IP of wan1....another time wan2...again wan1....and then keep "Waiting...."...and repeats everytime.
This is following the How to...pfsense+load balancing+squid+floating rule...
-
Anybody got this working with load balancing? I just can't get it to work if one of the nodes is down. It either craps out with invalid request or just takes forever and all the pages just sit there, spinning.
-
Thx to DimitriS.
The tutorial Works perfectly for me. ;D
I found only one problem. I could not set the navigation to the squid on the loopback interface, but as the Ermal said, just putting the "tcp_outgoing_address 127.0.0.1" worked for me.
I have only one more question… how i can force a ip range to use one of gateways. I tryed to create a LAN rule but not worked well...
EG: I need the traffic comming by 192.168.1.10 to 192.168.1.20 use the WAN2.
Thx and sorry for my google english :D
-
Well… After some days, the balance go to space!
All connections use the default gateway... any ideas?
-
Hello guys!
I make some new tests today, and i have new results…
I created a new floating rule to DNS (53) as quoted by heper.
The squid seems to work well now.
Also seted my WANS without a Default WAN. Seems helped. Not sure.
Now my WAN group Settings:
WAN1 - TIER2 - MONITOR ON INTERNAL ROUTER OF ISP
WAN2 - TIER1 - MONITOR ON 8.8.4.4 GOOGLE DNSI do this because when the some of WANs reach the latency, the Links always go to another WAN... but still not using the two wans... for some reason they choose the one... probaly the lower ping
when one of then seems always online, on tier 2, they balance fine.
I'm little confused now ???
Look at SS
I still making new tests...
Thx again and sorry for my bad english
