Installation and Upgrades / Re: Squid is blocking pages of my Wi-Fi APs

I think that i finally found what was causing the problem: when i was looking at the zentyal dashboard i saw that the traffic shapinh module was running for a few seconds, then stopping, then running again (although i had the module disabled). I then enabled and disabled the module again and the problem with the blocked pages was gone!

Your point is wright, but you have to take into account that i work in an environment where i have to follow directions from the CEO-Owner of the company. These directions change from minute to minute, often being based in respect of the current mood of the CEO e.g block internet to the x person, but next minute gives the person an order to search something in the internet!!! Some computers can browse anything without being monitored, some have to be monitored, others have only some sites open, all computers have static IPs, except that of the CEO and some other laptops, CEO does not want his PC and some others to go through the proxy and thus be monitored, i know you must feel a bit dizzy by now... I am trying to find a solution to fit everyone inside and at the same time satisfy the CEO...

I was asked to restrict and/or monitor internet access to certain departments of the company, that is why i cannot have all workstations go through zentyal, but some

When i first tried zentyal, i tried with only the LAN interface, having as a gateway the router, it was not working, the client computers could not connect to internet at all. I then used the wan interface with a static ip from another subnet, the same result. Then, i followed this post: http://forum.zentyal.org/index.php?topic=5532.0 and the problem was solved, everything was working. The setup i have is identical as the photo of the post shows. I have to use transparent proxy, because i do not want to mess up with browser modifications.

This is my routing table of zentyal:
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 br1
192.168.1.0     *               255.255.255.0   U     0      0        0 eth1

I can see that the eth1 gateway is not configured as 192.168.1.1 (however in zentyal dashboard i have it configured), maybe that is a problem, what is you opinion?

You are wright, wan goes through the router also, 192.168.1.1. DHCP is provided from the router, which is configured to give itselve as a gateway, so any pc with DHCP do not get through zentyal. All of the Wi-Fi routers have static IP, as all the computers of the network. I use DHCP only for visitors of the company and some laptops. I do not use vlans

I tried static on another subnet, it was not working. The setup as i have it is working fine. All the workstations that use the proxy are accessing internet and intranet fine. The problem started yesterday, when, for no particular reason squid started to block only the IPs that belong to the Wi-Fi routers, without the routers being configured to go through the proxy.

It has two interfaces, one for LAN, bridged and one for WAN. Zentyal is using as a gateway the router. DNS is getting from the router and the ISP. The problem is that my PC and the Wi-Fi APs do not go through zentyal, they use the router (Vigor 3300) directly for gateway and DNS, so squid should be impossible to interfere in their communication, yet it does! When i stop squid, the problem is fixed, but i need to find why squid interferes in a communication which does not go through it.

Installation and Upgrades / Squid is blocking pages of my Wi-Fi APs [SOLVED]

« on: November 21, 2013, 02:16:05 pm »

Hello,
    I am facing a very strange problem with zentyal and squid. I use zentyal as a transparent proxy for some of the computers of our network. e.g 192.168.1.8-192.168.1.70. I have setup these computers to use gateway and dns the ip of zentyal interface, e.g 192.168.1.2. My router is 192.168.1.1.
                          The rest of the network computers (which i do not want to pass-through the proxy) and the Wi-Fi access points use as gateway and dns the router (192.168.1.1).

                 The strange problem is that when i try to access the Wi-Fi access point's page (192.168.1.151) i cannot, even though my pc is not configured to use the zentyal proxy, it goes through directly to the router. When i stop the squid module from running on Zentyal, i can access the page again!!!
