Server :: Bridged Router / Modem Setup - Squid Transparent Proxy

May 19, 2010

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?

Networking :: Transparent Squid Proxy Setup

May 6, 2011

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.

Server :: SQUID 2.7.x And 3.1.x Won't Work As Transparent Proxy ?

Oct 16, 2010

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.

Server :: Squid With Transparent OR Authentication Options?

Mar 3, 2010

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.

Server :: Transparent Proxy In Squid Not Functional

Jun 3, 2009

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.

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.

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

Networking :: Squid As Local Transparent Proxy

Sep 28, 2009

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.

Security :: Transparent Firewall With Squid / Dansguardian?

Feb 23, 2010

I am looking to redesign my network which I'll get into bellow but basically i am looking to setup an transparent/bridged firewall with squid and dansguardian. However, I want to require LDAP authentication to access internet. You'll understand why from diagram below.

My question is, since bridged firewalls operate at layer 2 and have no/require no IP address, can you access higher layered apps with them? Example would be to have the proxy authenticate to LDAP system to check for valid user and valid net permissions, server has to somehow send a reply back, so without an IP, this can't happen right.

Below are two designs I am looking into implementing. Everything Internally will be Authenticated against LDAP with a small possibility of some public servers using LDAP too, but in my way of thinking anything using LDAP would should be behind the router on private link. FYI, the PROXY and the Linux Router would be two physically separate systems. So I guess my second question would be, can systems outside private network access limited internal services securely and be restricted at the same time?

Code:

Option 1:
(TRANSPARENT)
------------ -------------
| CBL MODM | ---------> | PROXY/FW |
------------ -------------

Networking :: Configuring Squid As Transparent Proxy In RHEL5?

Jun 11, 2009

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

Networking :: Iptables - Set Up Ip Table And A Transparent Squid Proxy

Nov 10, 2010

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.
