PfSense Squid Proxy for Multi-WAN

[hyrol]

Step Multi-WAN LoadBalancer with squid. I separate post in every step to simplify the configuration.
I'm confused on step 3 you mean whether floating or routing. I am waiting for your decision.

Hi,

thank you for the tutorial. Which IP address do I have to enter into "wpad" files when using different VLANs/interfaces?

Thank you.

[jikjik101]

i mean this:

DNS Forwarder
Enable DNS Forwarder

DHCP server
In Additional BOOTP/DHCP: wpad.dat, wpad.da and proxy.pac

Create wpad.dat, wpad.da and proxy.pac
Use vi editor to create file wpad.dat, wpad.da and proxy.pac

I have a DNS fowarder but without the wpad thing.

Thank you.

IP Address option depends on the current selection in the squid proxy interface, refer to the first post of the second picture.

What results did you get, I've never tried it. If successful it is good news.

Hi,

thank you for your response. But the picture shows just one interface (LAN) which is a listening interface on squid. I do have 6 different (V)LAN interfaces which are listening interfaces of squid but as far as I can see I am only able to create one wpad file.

So let's say I Have a host-A in VLAN-A which is not allowed to talk to VLAN-B (firewall rules) then how would it work if the IP of the wpad file is the interface IP of VLAN-B ?

Thank you!

try this…

function FindProxyForURL(url,host)
{
if (isInNet(host,"your.vlan.ip.address","your.vlan.subnet.mask"))
   (isInNet(host,"your.vlan.ip.address","your.vlan.subnet.mask"))
   (isInNet(host,"your.vlan.ip.address","your.vlan.subnet.mask"))
   (isInNet(host,"your.vlan.ip.address","your.vlan.subnet.mask"))
return "DIRECT";
else
return "PROXY your.pfsense.ip.address:port";  DIRECT";
}

What you say is true, I have tried to remove the step, it can work.

Skip this
DHCP server
In Additional BOOTP/DHCP: wpad.dat, wpad.da and proxy.pac

Create wpad.dat, wpad.da and proxy.pac
Use vi editor to create file wpad.dat, wpad.da and proxy.pac

For some reason, this setup not working on pfsense 2.1 and squid 3.3.4, my box was working very well with 2.0.3, but now it´s not with 2.1, any ideas?

[srk3461]

Nice way summing it up!  Thanks!

@hyrol:

Firewall Floating rules
Squid proxy use port 80 and use interface WAN, WAN it's default for squid proxy server
Select Gateway: Multi-WAN

Till Last week i was using Version 2.0.2 now upgraded to 2.0.3
Thanks!!!
The following tutorial helped me alot
http://securite-ti.com/pfSense_Web_Proxy_with_multi-WAN_links.pdf

I have some doubts [Confused]
My Scenario:
Configured my Gateway in Fail Over mode. [WAN1–-Tire1, WAN2---Tire2]
I want to make my Tire2 connection as default Gateway for 15 LAN Users. Does the policy based routing will work since WAN1 is the default for squid proxy server.
I have tested it but some times the Traffic goes through the Tire1 [Especially for DHCP Clients]

Interfaces: Lan Protocol: ANY Source: LAN IP Destination ports: ANY Gateway: WAN2GW

All configurations are same as shown in the PDF Tutorial. Do the same configurations will work on Version 2.0.3

[AMD_infinium05]

has anyone tried this on 2.0.3 ?

I have tried it earlier and I think i have messed up…... i have removed packages and revert to original settings, now my internet is working fine with load balancing, and failovers.

ON
2.1-RC1 (amd64)
built on Thu Aug 15 16:30:12 EDT 2013
FreeBSD 8.3-RELEASE-p9

I solved by activating "Allow default gateway switching" option in Advanced configs (failover only) and removing all floating and NAT rules..
Hope this helps…

that is not solved, it still has 2 problems that aren't an issue for your specific use.
It doesn't help with loadbalancing or when someone has more than 2 WANs of which 1 WAN reallly should not do http traffic (because it is reserved for other use like VoIP, or because the ip can't be known publicly etcetera)

It really is a stupid bug in 2.1. Worse is that 2.0.x had a bug that failover doesn't work for connections like VoIP/SIP so going back isn't an option either, at least for me… really nice

Finally, after a long time trying pfSense Squid Package + Multi Wan and I have managed to find its way in a deadlock.
pfSense 2.1 Squid Package + Multi Wan, no longer using the Floating Rules, but using the Interface Groups.
Good Luck Everyone.

Thanks, and congratulations!

What version of squid and squidguard are you using?

Please send a screenshot of your system->routing screen showing your default route.

[niebla]

Created the interface group, but how are you getting squid to use the group and not the default gateway?

[hyrol]

Still configure the same as pfSense 2.0.3 Squid Package Multi Wan, only changes to the Floating Rules to Interface Group.


[niebla]

Thanks but I am not seeing where or how you have used the interface group.
