      Version of PFSENSE: 1.2.3-RELEASE

      Hi.

      I been forced to turn off snort until I get a solution. Snort is banning my teamspeak3 users.

      The Ban is not triggerd directly first after some time.

      How can I disabable the rule that trigger bans on my Teamspeak 3 users?

      I tried adding Suppress rules but dosent work:
      suppress gen_id 122, sig_id 22
      suppress gen_id 122, sig_id 24

      Would love to get some help with this problem.

        That's not a rule but the portscan preprocessor. You need to disable the preprocessor, though I'm not sure how to do that with pfSense.

          To completely turn off that alert type;
          Go to the snort tab called "snort_preprocessors.php", then uncheck the "Portscan Detection" option.
          Thats all you have to do.

          The suppress rule you posted looks good to me. Did you remember to save/restart the snort interface ?

            Yes I can disable the portscan under preprocessors but its not a good solution I think.
            Still the only thing that works, my suppress rules do nothing (even after restarts)

            I wish I only could disable all alerts on port xxxx

            Would be awsome to be able to exclude some ports from all kind of checks.

            Then I could be able to protect myself from portscanners. (now I can't if I need teamspeak3 on my server)

            Will there be any solution for this for next version ?

              gen-msg.map File says were using the right sids.

              Oh I forgot to mention, try flipping the numbers.

              suppress gen_id 22, sig_id 122
              suppress gen_id 22, sig_id 122

                Sorry it diden't work to change the supress rule, still banning the users. Only thing that works is to disable Portscan Detection :(

                    If you know all their IP addresses or a IP range, add it to the whitelist. I do this for my work's IP range and it works like a charm. If it didn't, I wouldnt be able to OpenVPN because a block rule would be auto-created because of the portscan preprocessor.

                      Whitelisting is a crazy thing todo if you ask me. You never know what other people got on there computers.
