Server :: Make Squid 2.6 Stable As Transparent Proxy Server?
Dec 22, 2010
I want to make a transparent squid proxy server in centos. The squid proxy version is 2.6 stable. I made a normal squid server but want to make it transparent so that users do not need to enter the proxy settings in web browser. Even i searched about this on google but not getting it properly.I have two lan cards on centos system. ETH1 used for LAN and ETH2 used for WAN. And in this squid.conf i written "http_port 172.16.31.1:3128 transparent" and i also added a rule in iptables which is "iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128" but still i have to enter proxy settings at client's web browser to use internet

I have installed and tried both squid version as transparent proxy but they just don't work.
I have eth0 which is where my internet comes in and eth1 which is my local network 192.168.1.0/255.255.255.0.
My default firewall policy is to drop input output and forward, i have already set my firewall to accept and workout the squid and it is working.
Here is the relevant rules i have on my firewall:
Code:
Here is the sample conf i am using for squid:
Code:
Always_direct allow all When using version 2.7.x i was able to make it transparent when i used the below rules:
Code:
I readed the Docs on the squid page but the above rules can't be reproduced to 3.1 and i don't wish to use such rules to make it transparent or hidden so i want some help to figure out why it inst transparent.

I am using Fedora 9, I have compile the squid with source code, i also deleted the old RPM of squid. i then edited the squid.conf in /usr/local/squid/etc and set http_port 3128 transparent and allowed in my acl to my local network but the transparent proxy is not working. if i remove transparent proxy then squid works fine. when i try to make it transparent the squid access.log file does not show any request coming to it (no activity). i have also forwarded all the incoming traffic to squid port 3128. Can anybody tell me why my transparent proxy is not functional.

I'm using a Debian box as a gateway. I'm planning on bridging my DLink 604T modem/router so that traffic on the LAN goes to my gateway (which only has one NIC). The Debian box is running a PPPoe application which I'm hoping to log into the ISP through the DLink. I plan to configure the box as a squid transparent proxy. Most Howtos I've seen use NAT with 2 NICs, eth0 for the LAN and eth1 for the Internet. Any step-through to set up NAT for this?

How to make squid proxy transparent?I have configured a Squid proxy server with some ACLs but we have to check from client side whether those ACLs work or not ,I have to open their firefox and manually enter my machine's i.e. proxy server's ip, only after entering this ip , Those ACLs work properly.But now I want to make it work without manually entering the proxy on clients machine.I guess transparent proxy is the solution, but how to configure it/Please guide me and I am one of the machine in LAN.

I am trying to set up my squid3 proxy as a transparent proxy - right now, I have to manually configure browsers to access via proxy. I understand that I have to put some rules into Iptables and also some further directives in the squid.conf.
I have a couple of specific questions. The proxy server is running on a Ubuntu 10.04 workstation and this machine also acts as a dhcp server for the network. I have just one subnet , namely 192.168.0.1-254 There is only 1 network card. Is it much easier to put in a second network card or is it just as easy to configure the existing lan card as a dual IP?
Is it necessary to configure these 2 IP's ( whether they are via 2 lan cards or dual IP on single card ) to be on different subnets. i.e ETH0 192.168.0.1 and ETH1 192.168.1.1 or is ok to have something like ETH0 192.168.0.1 and ETH1 192.168.0.254 ( where ETH0 is the one facing the LAN and ETH1 points to the modem router / switch i.e The Internet ) Where specifically do I save the Iptables rule configuration file and what must I call it ?

I am trying to set up squid to make switching proxies easier. I have a laptop which I use at work and at home. At work, I need to connect to the internet via a authenticated proxy. At home, I connect directly to via mobile broadband. So I end up switching proxy settings twice daily, which is just irritating! To solve this I want to set up a system whereby I never have to worry about a proxy - my browser sees a direct internet connection which squid (on my computer) intercepts and forwards either to the mobile broadband connection or to the work proxy (along with the required authentication) depending on which is available. I've read various articles on how to do clever things with iptables and squid, but I don't understand enough of the networking jargon or concepts to know when I need to change to make it work in my situation, or if it is even possible.

I have set up squid3 and dhcp server on my Ubuntu 10.04 box with IP address of 192.168.0.160. Single network card.Squid runs on port 3148. Everything works fine for the users provided that I set up the proxy details manually on each client pc.I want to set up the Squid to run as a transparent proxy and after reading around I have done the following.In the Squid3 conf file I have entered http_port 3148 transparent.Dropping to Root ( sudo -i )However the transparent proxy does not work and if I enter iptables -L I can see that the rule above has not been retained. The default rules in iptables only show up.

Need a bit of help from the linux community. Lately, I have been trying to configure squid as transparent proxy on my server running on RHEL5. I had gone through few articles on web abt how to configure it and configured squid accordingly adding http_accel_xyz settings and then configuring the NAT using iptables. But while restarting squid there were warnings about "unrecognized: http_accel_..." in parseConfigFile.What I could get from these is that probably I need to recompile squid adding transparent proxy support. I downloaded the new squid 3.0 and tried to compile it.But unfortunately, the 'make' command fails giving library errors.I have been stuck with t now as the new squid does not compile and old one does not support the transparent mode.could compile the new one and what supporting libraries do I need to compile it successfully and also from where can

I need to set up an ip table and a transparent squid proxy as followed: I have 3 machine: Machine 1 works as a squid proxy. It has 2 interface eth1 and eth2.
eth1: 192.168.99.2 (Connect to eth1 of machine 2)
eth2: 192.168.98.2 (Connect to eth1 of machine 3)
machine 2 works as a webserver
eth1: 192.168.99.4
machine 3 works as a web client.
eth1: 192.168.98.4
my responsibility is to send all tcp traffic from machine 3 at port 80 to my squid proxy. In order to fulfill the tasks, I have edited the squid.conf as followed: Code: http_access allow localnet http_access allow localhost and in machine 1, I tried 2 ip tables command: Code: iptables -t nat -A PREROUTING -i eth2 -p tcp --dport 80 -j DNAT --to 192.168.99.2:80 iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 80 I don't know if it is right or wrong.

My skill in fedora linux is all acquired by reading online and trial and error. I manage to set up my squid 3.0 proxy server in fedora 11. It is working smoothly as I wanted it to be. I have one client who is running bittorrent that drags all the bandwidth of our network.The problem is I cant make my server work tranparently. I want to make transparent proxy so that it can support my wireless router and I want to control the bandwidth to a fair level for everyone without them knowing.
Please somebody help me configure iptables in step by step, specifically in fedora 11. And all other necessary configuration needed to run my transparent squid 3.0 proxy in fedora 11.I know there's a lot of Linux Genius here that can help. Please help me I needed it badly.

I have a squid server set up with two ports:
http_port 3128 transparent
http_port 3129
Port 3128 is set up for transparent proxying (ie, if you send a request to the internet, iptables forwards it to 3128) Port 3129 is just a regular port. If you connect to 3129 directly, you get prompted for a password:
Code:
auth_param basic program /usr/lib/squid3/ncsa_auth /etc/squid/squid.passwd
auth_param basic children 2
auth_param basic realm Squid proxy-caching server
acl password proxy_auth admin
http_access allow password
And this is actually working also. If someone signs then they are able to access unrestricted browsing (with squidguard). However, if they don't, they are transparent-proxied and have restricted browsing. The problem is I keep getting /var/squid/cache.log hits:
Code:
2010/03/03 17:11:04| ACHChecklist::authenticated: authentication not applicable on transparently intercepted requests. Basically evertime there's a transparent request, it throws a warning.
