SQUID and Load Balancing doesn't work!!!! I tried for a week but nothing :'(
-
CONCLUSION:
SQUID and LOAD BALANCING doesn't work together.. why??? well is a little hard to explain, you can see more details in picture below, Squid only work with DEFAULT GATEWAY not with LOAD BALANCE GATEWAY, Squid choose one gateway, and this gateway is "DEFAULT GATEWAY"
See the pictures please
PS: All configuration is OK including the floating, Load Balancing works fine and Squid also.. but when Squid and Balance works, Squid only works with one Gateway or one WAN INTERFACE.. it can be WAN or OPT1.. I thought that Squid was working with Virtual Interface created by Load Balancing i.e that two WANs provide cache
-
Is it not possible to make the gateway-group default? I don't have Multi-WAN, so its only a thought… Maybe wrong.
-
Can you send your config.xml this is not going to take you/me anywhere like this.
-
Here I send config.xml I hope all is OK.. if you have other thinks please only tell me..

Is it not possible to make the gateway-group default? I don't have Multi-WAN, so its only a thought… Maybe wrong.
Well Squid only work with the local IP 127.0.0.1 then Squid works with default gateway, it doesn't work with gateway-group, you can see in the picture below an example, if I take OPT1 like defaul gateway then Squid works with OPT1 interface, if you take WAN like default gateway then Squid work with Wan interface.
-
The only problem i see in your config is that you might want to try
from:<address>127.0.0.1/24</address>
to:
<address>127.0.0.1/8</address>
afterwards i need access to the system.
-
All work fine, SQUID + LOAD BALANCING, but apparently, SQUID only works with default gateway, if you remove WAN or turn off ADSL telefonica, you will not have internet but will continue to operate Squid
PLEASE SEE THE PICTURE BELOW.
SQUID + LOAD BALANCING DOESN'T WORK
-
Do you by any chance have sticky-connections active?!
-
:-[ I don't have sticky-connection you can see below in the picture, now I prove again the squid and load balancing and nothing
-
anyone have this working?

I know this is an old post but I'm seeing the same symptoms as the OP, squid works fine with load balancing but if the default gateway modem is turned off/unplugged, clients are unable to browse the internet.

How you are creating rules?
-
Hi Ermal
Action: PASS / Quick: TICKED / Interface: NONE / Direction: OUT / Protocol: TCP / Source: 127.0.0.1 / Dst: ANY / Dst Port Range: 80 / GW: Multiwan
I think that rule is correct, appologies if I have it wrong!
Thanks
Slam
EDIT
I have squid bound to LAN/CP1/CP2, all 3 interfaces have gateway also set to Multiwan in their respective rules, I dont know if thats relevant.
-
You need direction out and source any.
You can even try with direction out and source WAN ip to try to tighten it. -
@ermal:
You need direction out and source any.
You can even try with direction out and source WAN ip to try to tighten it.I've tried the above suggestions without any luck.
On my testbed, I have 2 wans, currently wan2 is set as default gw, the interface is hooked up to a hub so that the interface shows as up as active, although the hub is not connected to anything. (I needed its modem for a production box)
wan1 is connected to a modem and not set for default gw.
I have tried almost everything, from unticking "Block private/bogon networks" to setting static IP and DNS on my client machine.
I hope the following can helps you track down the problem, if you need anymore information Ill be happy to help.

Are you using Manual Outbound NAT?
pfctl -vvsr is the output i want to see actually.Do you have issues on traffic with this rule?
Please show me even a pfctl -vvsnWhile there can you try enable manual outbound NAT and add a rule with source any and external your wan1(94…../20) gw?
See if it works. -
Ive included output for the those commands
pfctl -vvsr - command1.txt
pfctl -vvsn - command2.txtI dont use outbound nat and dont even know how to use it, I got stuck when I tried to follow your comments, I've sent you a pm with details if you like access to the box yourself.
Thanks
Slam
-
Check out now it should be ok from what i see!?
If you want to tighten you can change the any in the outbound nat rules at the end to the respective interfaces subnet.
-
Ive just gave it another go, my browser just sits there trying to access the internet without any luck
is it ok to leave those other rules in outbound nat? will they interfere with the rules I have for the interfaces? shall i reboot and try?
Thanks
Slam

Just try out with static port ticked on those rules.
