Squid Returned to Packages *** PLEASE TEST ***
-
Hello,
I tested the proxy and found out that, wenn you enabled the proxy in normal or transparency mode the NAT for the clients who use the proxy doesent work.
I searched for this in the internet and found out that you should enter
forwared_for off
in the squid.conf.
Then the clients which use the proxy will be NATted to the WAN IP.Please can you fix it.
Thanks,

for the old squid package i once made a diff… when this could help you'll find them here:
http://pfsense.trendchiller.com/squid/
But as I said these were for the old versions of the squid package…
-
hi again
where is the file squid.conf, and in what line i should insert the forwarded_for off???
thank you
-
have a look in /usr/local/etc/squid/squid.conf
then add the line somewhere near the beginning of the acls in the file…

Hello,
if someone interested here are my version of
squid.inc

What version squidGuard worked with current squid version?
-
Since squidGuard hasn't been in development for a number of years, the latest version in the FreeBSD ports tree should be perfectly adequate. I've used it before (not on pfSense) with the squid26 port.
-
I have pfSense 1.0.1 and latest official squid package (squid-2.6.5) from this topic
When i test self sG package gui with this on local pkg_config.xml (xmlrpc):
```
<depends_on_package_base_url>http://ftp13.freebsd.org/pub/FreeBSD/ports/i386/packages-6-stable/All</depends_on_package_base_url>
<depends_on_package>squidGuard-1.2.0_1.tbz</depends_on_package>this download previous version squid-2.5.14_2.tbz and install them ??? In **pkg_info** i looking both versions of **sqiud** What i must do for use squidGuard whith installed newest version squid (not download previous version)? ps: i only make webGUI for squidGuard for existing hidden in pkg_config.xml _squidGuard package_ -
Error in /usr/local/pkg/squid.inc, line #639
'max_download_suze' must be changed on 'max_download_size'

just installed squid and find it to be quite nice. The interface is completely different from what I expected. Not as powerful as I would like it to be. Probably cause I am used to webmin.
Anyway, some of the features I needed are not in the gui. Can I port over my own squid.conf and apply it there? I understand I won't be able to edit the squid.conf later using the gui. I am okay with that as I can edit the file manually. Will that work?
-
Yes You can edit squid.conf manually But don't run gui after - conf will rewrited
-
If you want to write your own conf files, just edit the squid.sh file in /usr/local/etc/rc.d/squid.sh
Add the startup flag to point to the squid.conf that you write yourself.
The webgui won't work for changes anymore, but you won't get your conf file rewritten every time the box restarts either.
Also, webmin runs on a pfsense machine
pkg_add -r webmin
run setup.pl instead .sh
Boom, you have webmin. -
-
Boom probably is a good word for it, I wouldn't use webmin to change anything, but you can if you want…hehe
-
I'm having trouble with setting up mac filtering, I was wondering if that option was included in the "return" of squid?
-
On transparent mode squid blocked access to 127.0.0.1 (from php to self system), but access trought LAN ip worked. It's bug or no?
