Not sure why the web proxy is blocking services like “apt” Web Proxy is enabled on Green, Transparent proxy is disabled. Can’t update a linux box doing sudo apt updateget blocked - connect (111: Connection refused) Cannot initiate the connection Could not connect to archive.raspberrypi.org:80 …

Hi, apparently, apt continues to try to establish direct internet connections (though I am surprised to see these attempts ending in an ICMP reject rather than being silently dropped - did you configure your IPFire according to that?). Please double-check that apt is really using the configured pr…

I haven’t configured the proxy for “apt” but I have allowed all standartd ports 80 # http 21 # ftp 443 # https 1025-65535 # unregistered ports 280 # http-mgmt 488 # gss-http 591 # filemaker 777 # multiling http 800 # Squids port (for icons) I even tried using a browser and got refused as well. O…

I think you have a rule that blocks all the traffic on the red interface that is not directed to the proxy. Setting squid to cache traffic on other ports has no effect on that rule. Hence when APT try to connect directly (because it was not being configured to use the proxy) your firewall intercept …

As he wrote this is also with webbrowsers. [image] trish: I even tried using a browser and got refused as well. Once I shutdown proxy all is good. :face_exhaling: Set up the webbrowser to communicate with the proxy directly to see that it works (don’t use global / system settings). As alrea…

Hi, I have several “Devels” running here - and had similar problems. Perhaps this helps: Check your apt configuration. In my case I had to edit /etc/apt/apt.conf (Ubuntu 20.04.4 LTS) to read: Acquire::http::Proxy "http://[PROXY_IP]:[PROXY_PORT]/"; Acquire::https::Proxy "https://[PROXY_IP]:[PROXY…

[image] fischerm42: Do you have IPS running? I ran ET emerging-policy rules and had to deactivate "ET POLICY GNU/Linux APT User-Agent Outbound likely related to package management" which showed up in IPS logs. This stopped APT for me also! [image] Problems with DNS C…

Thank you , a lot of great comments. [image] cfusco: I think you have a rule that blocks all the traffic on the red interface that is not directed to the proxy. That was my suspicion too, In Firewall options, but I don’t think it will apply on Green. Firewall options for BLUE interface Drop…

[image] trish: At the end I think it was the Proxy service blocking APT, I tried changing to a different mirror, but got blocked too. I shutdown the proxy and have no issues anymore. This is what I do not understand, if your Debian machine is not set to use the proxy, and there is no transpa…

Yes, I agree, not just a single Debian machine but all the machines that I tried were doing it, which were Raspberry OS, and a few Ubuntu… When I get time, I will turn the Proxy back and try more ideas.

I just installed MX and have the same issue. I’ve set DNS query to TLS, so I’ve added http(s) on the repo mirrors and it connects fine now.
