When I want to download talos for registered rules for IPS it returns with can not download rules . I tried to go to snort website but cloudflare stopped me. I checked the snort website without ipfire and i was able to open the website.I should mention that there is no firewall rules in ipfire. help me to solve this issue.
let me explain this. I installed ipfire (without any configuration) and tried to open snort website to check but it did not opened (cloudflare 1020 error) then I removed ipfire from my network and I was able to open snort and talos website. I think there is something wrong in ipfire which would not let me open snort website and also download talos rulesets.
That problem is related to violating a firewall rule of Snort set by Talos.
Talos also provide clamav and the clamav signatures are provided through cloudfare as well and if the Freshclam signature downloader access the site too often then your IP gets blocked. I have seen that be reported on the clamav mailing list.
Looks like you need to contact probably Snort to find what the reason for the violation was and to get removed from their block list. That was how it worked with the Clamav cases that I saw.
The reason you can access the site without IPFire is that the details of the machine making the connection are different.
