PfSense 2.2: Squid 3.4.10_2 pkg 0.2.6 redirection not working in transparent mode

Steve Evans

This is a follow-on from THIS thread. I've overcome the hurdles highlighted there with respect to the /tmp/rules.test.packages syntax error, so I thought I'd best start a more focussed thread.

If I enable tranparency mode on my LAN (on interface msk2) the only difference I see in the output of

pfctl -s rules -s nat

is the addition of

rdr on msk2 inet proto tcp from any to ! (msk2) port = http -> 127.0.0.1 port 3128

which appears correct.

I have a firewall rule setup to allow outbound traffic from my LAN on port 3128 on which I've enabled logging for the moment.

If I manually enable the proxy on my laptop (MacBook Pro if that's of relevance) and access a webpage I see the following in my firewall log and the accesses are recorded in /var/log/squid/access.log.

If I turn on the transparent proxy and attempt to access the same webpage, the redirected access is logged as shown, but nothing appears in the squid access log, and the browser hangs.

Why might this be?

Thanks,

Steve

Steve Evans

The notable thing about the screenshots above is that in transparent mode the request is forwarded to the loopback interface. Squid is not listening on that interface when not in transparent mode.

: netstat -an | grep LISTEN | grep 3128
tcp4       0      0 10.5.1.1.3128          *.*                    LISTEN

However in transparent mode it starts listening on loopback.

: netstat -an | grep LISTEN | grep 3128
tcp4       0      0 127.0.0.1.3128         *.*                    LISTEN
tcp4       0      0 10.5.1.1.3128          *.*                    LISTEN

Why then is nothing being logged?

Steve

Logged on squid or system logs?

If you have enabled logs, the default dir is /var/squid/logs instead of /var/log/squid.

Steve Evans

Squid logs. I changed the default logging directory some time ago (under 2.1) as all the other pfSense logs are under /var/logs. I'll switch it back in case that makes a difference.

When accessing the proxy direct I see the expected per access entries in access.log.

Steve

Steve Evans

Regardless of logging path, using squid direct I see logging, such as

Not sure if it's relevant, but I'd noted the following in cache.log.

Not sure why this should be so I'd enabled the Disable ICMP option on the General settings tab which then gives a clean start thus.

It's not too clear what happening from a browser perspective, but using telnet may be a little more informative.

From my laptop

$ telnet news.bbc.co.uk 80
Trying 212.58.244.56...

and then nothing.

Whereas

$ telnet pfsense 3128
Trying 10.5.1.1...
Connected to pfsense.
Escape character is '^]'.

clearly connects.

Trying the connection locally from the pfSense console

: telnet 127.0.0.1 3128
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

works.

This suggests that the redirection is not working, or at least squid is not accepting redirected connections.

This is making me think that the redirected request may not even be reaching squid. I've tried adding a pass all rule to the firewall, but this had no effect. As mentioned before I see the firewall logging TCP packets being passed on port 3128 so I'm somewhat confused.

Steve

Steve Evans

I note the following applicable rule even if I disable my explicit rule such that I see the firewall log blocking access to 127.0.0.1:3128.

: pfctl -s rules | grep 3128
pass in quick on msk2 proto tcp from any to ! (msk2) port = 3128 flags S/SA keep state

I this state I see, from my laptop, immediate refused connections thus.

$ telnet news.bbc.co.uk 80
Trying 212.58.244.56...
telnet: connect to address 212.58.244.56: Connection refused
Trying 212.58.244.57...
telnet: connect to address 212.58.244.57: Connection refused
telnet: Unable to connect to remote host

If I re-enable my explicit rule such that the firewall logs the packet being passed, I see the following rules.

: pfctl -s rules | grep 3128
pass in log quick on msk2 inet proto tcp from any to any port = 3128 flags S/SA keep state label "USER_RULE: Squid Proxy"
pass in log quick on msk2 inet6 proto tcp from any to any port = 3128 flags S/SA keep state label "USER_RULE: Squid Proxy"
pass in quick on msk2 proto tcp from any to ! (msk2) port = 3128 flags S/SA keep state

Then the firewall logs a packet passed, but telnet hangs as per my previous post.

If I disable transparency mode I see that the extra rule is no longer there.

: pfctl -s rules | grep 3128
pass in log quick on msk2 inet proto tcp from any to any port = 3128 flags S/SA keep state label "USER_RULE: Squid Proxy"
pass in log quick on msk2 inet6 proto tcp from any to any port = 3128 flags S/SA keep state label "USER_RULE: Squid Proxy"

Is this extra rule somehow broken?

Steve

marcelloc

Did you selected lan on transparent interface?

if you execute grep 3128 /tmp/rules.debug you should see two rules, one for redirect and other to allow traffic.

rdr on em1 proto tcp from any to !(em1) port 80 -> 127.0.0.1 port 3128
pass in quick on em1 proto tcp from any to !(em1) port {80,3128} flags S/SA keep state

Steve Evans

Hi Marcelloc,

Your assistance with this is much appreciated.

Yes, LAN is selected as shown below. Note that SkyPlus is an alias for my Sky+ box which historically has refused to work with VOD services if proxied. It's presence in the config makes no difference.

I see the following

: grep 3128 /tmp/rules.debug
SquidProxy = "{   3128 }"
rdr on msk2 proto tcp from any to !(msk2) port 80 -> 127.0.0.1 port 3128
pass in quick on msk2 proto tcp from any to !(msk2) port {80,3128} flags S/SA keep state

Should I need to define a rule to allow LAN access to port 3128? It looks like the above should cover it, but this alone results in blocked packets.

Thanks,

Steve

Steve Evans

OK, so I just found the following in /tmp/rules.debug, between my rule for port 3128 and the one added by squid.

block return  in log  quick  on $LAN inet from any to any tracker 1422139962  label "USER_RULE: IPv4 block"

As I block all traffic by default and only allow out what's explicitly permitted, and the squid rule is simply being appended to the ruleset, this makes sense now.

I'll try amending my rule to be an exact match and report back.

Steve

Steve Evans

So, due to my use of aliases my rule did show up with your grep.

: grep SquidProxy /tmp/rules.debug
SquidProxy = "{   3128 }"
pass  in log  quick  on $LAN inet proto tcp  from any to any port $SquidProxy tracker 1422139913 flags S/SA keep state  label "USER_RULE: Squid Proxy"

I realise my rules for proxy access were too weak as they would have allowed somebody on my network to use alternate proxy, so I've modified my rules thus, but this hasn't fixed transparency mode. :(

pass  in log  quick  on $LAN inet proto tcp  from any to $pfSense port $SquidProxy tracker 1422139913 flags S/SA keep state  label "USER_RULE: Squid Proxy"
pass  in log  quick  on $LAN inet proto tcp  from any to (self) port $SquidProxy tracker 1422382055 flags S/SA keep state  label "USER_RULE: Squid Proxy loopback"

Thanks,

Steve

marcelloc

Include 127.0.0.1 on your 3128 rule too.

Steve Evans

Is that not the same as self?

Steve

marcelloc

@Steve:

Is that not the same as self?

I don't know if is lan ip or any local ip (including lo0)

Steve Evans

Changed rules to

: grep SquidProxy /tmp/rules.debug
SquidProxy = "{   3128 }"
pass  in log  quick  on $LAN inet proto tcp  from any to $pfSense port $SquidProxy tracker 1422139913 flags S/SA keep state  label "USER_RULE: Squid Proxy"
pass  in log  quick  on $LAN inet proto tcp  from any to 127.0.0.1 port $SquidProxy tracker 1422382055 flags S/SA keep state  label "USER_RULE: Squid Proxy loopback"

No improvement.

Steve

Steve Evans

To prove the point that the redirected transparent connection is not getting through to squid, I stopped the squid process and then ran the following on the pfSense console.

: nc -l 3128

I then telnetted to pfsense from my laptop and a connection was established and characters passed.

$ telnet 10.5.1.1 3128
Trying 10.5.1.1...
Connected to pfsense.scevans.com.
Escape character is '^]'.
hello

: nc -Dl 3128
hello

I repeated trying to telnet to port 80 on news.bbc.co.uk which should have been directed by the redirect, and no connection was made.

Steve

Steve Evans

I've now turn off transparent mode and then added a NAT rule.

This appears in /tmp/rules.debug thus.

rdr on msk2 proto tcp from any to !10.5.1.0/24 port 80 -> 10.5.1.1 port 3128

I see the resulting packet to port 3128 being passed by the firewall in the logs on an attempt to access an external host on port 80 from LAN.

With squid stopped and running

nc -vl 3128

instead on the pfSense console this connection attempt is not seen.

Contacting pfSense directly from the LAN on port 3128 does get through.

Clearly the HTTP request gets redirected to port 3128, makes it through the firewall, but then gets lost.

I'm stumped.

Steve

marcelloc

May be not related to the issue but do you have pfsense gui redirect enabled under system -> advanced?

All my testes were on pfsense 2.2 amd64, no cf or nanobsd.

What 2.2 version are you using?

Steve Evans

I have the Disable webConfigurator redirect rule checkbox ticked as I have WPAD running on port 80 using the vHosts web server. Unfortunately iPhones etc don't use WPAD so I need transparency mode, but I've left it turned on for now.

I'm using the recent full 2.2 release.

I've just tried putting a pass all rule at the start of my LAN rules to see if that would fix any firewall issue, but it did no good.

Steve

marcelloc

2.2 amd64?

Steve Evans

I've just rebooted the firewall with all pf rules reverted to those in /conf.default/config.xml. This should eliminate any firewall rule peculiarities. I'll let you know how that works once it's up.

Thanks,

Steve

marcelloc

I have two users on portuguese forum with same version 2.2-RELEASE-i386 and same issue.

Maybe it's related to squid pbi package compilation under i386 system.

Steve Evans

Interesting.

Given that I see the lack of redirection with nc as well as squid I'm inclined to think this may not be an issue with squid at all, but rather with pf. That'd be quite a fundamental problem for pfSense!

I made THIS post in the Firewalling forum to see if that provides any insight. For now I'm going to see if a minimal pf configuration helps.

Thanks,

Steve

Steve Evans

With the default firewall rules, squid is still not working in transparent mode.

As you're seeing multiple reports of this, could you please raise a bug report that captures the collective experience.

I'll need to create an i386 virtual machine to get same problem. On all my labs, transparent proxy is working fine.

Now here's an oddity.

This is one of pbi behaviors. same binary, different folder, different results. (Imagine get all it working together :))

And here is the confirmation that pbi build on i386 is outdated

'--disable-ipf-transparent' '--disable-ipfw-transparent'

Go to amd64 and it will work :)

Thanks for your feedback

Steve Evans

Hi Marcelloc,

As I'm running on a Pentium-M on a Watchguard Firebox x750e I'm afraid that I'm constrained somewhat to only running 32 bit. That said, one of the great things about pfSense is it's a great application to run on older hardware, so thanks for keeping the i386 version alive!

How soon might a package update for i386 be forthcoming would you guess?

Thanks again,

Steve

Just wait core team to compile it again. The compile args were fixed few weeks ago but only amd64 was rebuild.

Problably you've enabled transparent mode but did not selected any interface for interception.

I am running 2.2-RELEASE (amd64) and transparent mode isn't working either.

Check package config again, it's working on my setup and on my labs.

Could you please confirm that my experiment using nc works in your setup. This will help determine if the issue is with squid or the firewall.

Thanks,

Steve

Just wait core team to compile it again. The compile args were fixed few weeks ago but only amd64 was rebuild.

I am running 2.2-RELEASE (amd64) and transparent mode isn't working either.

Hi Marcelloc,

Any idea when the new package might be available?

Thanks,

Steve

No. I'll ping Renato again and ask for a update to 3.4.11

Bump for i386 build:)

I'm also on a i386 box and i wonder if i should go with squid or squid3 ? i've had squid running under other circumstances, but not with pfSense on i386. Im already running pfBlockerNG with several alias lists, and i'd want squid/squid3 to not work for sites that are blocked there, obviously. Does squid3 transparent proxies 'bypass' the pfBlockerNG rules, or are the rules applied before the traffic even reaches it?

I think SquidGuard rule administering are a lot harder than in pfBlocker so i'd prefer to keep all the rules management there and have squid3 only do transparent proxying for the sites that pass the firewall.

PfSense 2.2: Squid 3.4.10_2 pkg 0.2.6 redirection not working in transparent mode
