Squid port 3128 and Firewall Rules

[mcury]

@JonathanLee Its blocking out connections, from pfsense to the host, with a default deny ipv4 rule?

Check with cat /tmp/rules.debug in the shell, search for that rule.

Do you have any floating rules ?

[JonathanLee]

@mcury Yes I have floating rules for traffic shaping

# default deny rules
#---------------------------------------------------------------------------
block in log inet all ridentifier 1000000103 label "Default deny rule IPv4"
block out log inet all ridentifier 1000000104 label "Default deny rule IPv4"

I suppose you have transparent proxy also enabled ? For systems that can't set a proxy by hand ?
If that is the case, disable transparent proxy for one second to see if it is not related to the rdr pass you have up there

[JonathanLee]

@mcury Yes I do have both, my XBOX uses the transparent side

Have you bypassed all other hosts that don't need transparent proxy in the Squid settings ?

Disable transparent proxy for one sec and test.

If it works, enable it again and try to bypass clients that are pointing to the proxy (explicit) in the transparent settings.

@mcury How do you bypass for example one host like 192.168.1.17 from the SSL intercept but still make it use the the transparent proxy?

1- Disable transparent proxy
2- You would have to create the transparent NAT manually, using a ! in the source, with that IP address.
3- That NAT would have to redirect outbound TCP 443 connections to 127.0.0.1 3128.

Test like that, if doesn't work, try to change the port in the 3rd step to 3129.

I think that will do it.

Note that you would also need to create one for port 80.

@mcury Thanks!!!! that helps a lot I no longer see double requests for everything and it all still works!!! The XBOX uses transparent and UpNp and all the devices that know about the proxy don't need the transparent!!! YES!!!
