      Hi everyone!

      I'm looking for some help to solve a strange issue with pfBlockerNG and OpenVPN.
      On pfSense I've both OpenVPN client and server. Everything worked fine until I installed pfBlockerNG. Then, every 2 times I restart pfSense, the service status shows that OpenVPN server is not working.

      The thing is: OpenVPN server actually works if I test it! I can connect as normal, it's just pfSense that thinks it's not working.
      If I reboot pfSense, then everything turns back to normal, and the problem reappears if I reboot once again, and so on.

      On boot, OpenVPN log reports this error:

      May 5 17:43:13 	openvpn 	30398 	TCP/UDP: Socket bind failed on local address [AF_INET]192.168.1.100:1194: Address already in use 
      

      192.168.1.100 is the WAN address. If I try to restart the service, i get a TUN/TAP device busy error, since it's actually being used.
      It doesn't help to disable pfBlockingNG, but if I uninstall it then the problem disappears.
      Another thing that "solves" the problem is to remove all the firewall's rules on OpenVPN, but then I have to manually add them again after reboot and remove them before the next reboot.

      What am I doing wrong? What did I miss?

      pfSense v2.3
      pfBlockingNG v2.0.12

        The only way I can see pfBlockerNG interfering with OpenVPN, is if you configured the DNSBL Port to use 1194?

        Can you describe your Interfaces? and are you using DNSBL?

          I tried DNSBL, but now it's disabled. I haven't changed the DNSBL's port, btw.

          This is the list of my interfaces:

          WAN - eth0
          LAN - eth1
          WIFI - wlan0
          CLIENTS - vlan1
          SERVERS - vlan2
          BRIDGE - between WIFI and CLIENTS
          VPN - used by VPN client

            BRIDGE - between WIFI and CLIENTS
            VPN - used by VPN client

            So if DNSBL is disabled, there is nothing else in pfBlockerNG that touches the ports. Could it be that a firewall rule is blocking something?

              I thought of it too, but I can't find any difference on the firewall rules from when I don't have pfBlockerNG installed and when I do.
              Plus the fact that it happens once every two reboots leaves me very confused…

                I don't think its an issue with the pfBlockerNG package… Try to post in the OpenVPN forum thread.

                  I've got pfSense at home and I wanted to put the lvl1 bluetack list in pfBlockerNG but when I get to that entry, it takes a long time for it to load and can make new DNS queries time out (I'm guessing since it's making changes to Unbound?)

                  Everything else is working fine.  Running on a AMD Athlon™ II X2 240 Processor with 3GB of RAM.

                  Do I just need to throw more RAM in there or is there something I can tweak to fix this behavior?

                  Thanks,

                  -Nick-

                    I guess that Level 1 Bluetack is a subscription list… Not sure how many IPs are in that list? But I assume that its an IP list and not a DNSBL list, so it should be added to the IPv4 Tab. It shouldn't timeout Unbound tho...

                      Hi all,
                      I’ve just tried to install pfBlockerNG on pfSense 2.3.1_1 and I got error message:

                      pkg: https://pkg.pfsense.org/pfSense_v2_3_1_amd64-pfSense_v2_3_1/All/pfSense-pkg-pfBlockerNG-2.0.17.txz: Not Found
                      Failed
                      

                      After quick check I found that repository contains 2.0.14 but not 2.0.17.

                          Hope someone can help I have outbound deny selected on the IPV4 list below

                          Alias Name Alias Description Action Frequency Logging
                          IBlock pfBlockerNG IBlock Deny_Outbound 04hours enabled

                          PRI1 pfBlockerNG PRI1 Deny_Outbound 01hour enabled

                          PRI2 pfBlockerNG PRI2 Deny_Outbound 04hours enabled

                          PRI3 pfBlockerNG PRI3 Deny_Outbound 04hours enabled

                          SEC1 pfBlockerNG SEC1 Deny_Outbound 04hours enabled

                          TOR     pfBlockerNG TOR Deny_Outbound 04hours enabled

                          MAIL pfBlockerNG MAIL Deny_Outbound 08hours enabled

                          Now I want to keep all the listed enabled but i keep getting some good sites blocked like dropbox.com.

                          Can someone advice how i can exclude these destination domains please. I have tried the advance rule outbound invert but when i do it locks me out of the firewall interface.

                            If an IP is getting blocked, then you can either: 1) Suppress the IP from the Alerts Tab 2) Create a new pfBlockerNG alias (Whitelist), and add the IP to the customlist and set the format to "Permit Outbound". Ensure that the "Rule Order" places the Permit Rules, above the Block/Reject Rules.

                            If a domain is getting blocked by DNSBL, then you need to suppress it from the Alerts Tab.

                                  The bogons is handled by the pfSense code not pfBlockerNG. Maybe try to disable and re-enable Bogons to see what that does. The package changes the max table entry in the advanced settings automatically so it shouldn't be that.

Ensure that the "Rule Order" places the Permit Rules, above the Block/Reject Rules.

                                      If a domain is getting blocked by DNSBL, then you need to suppress it from the Alerts Tab.

                                      BBCan- first off, great work. Been using pfblocker for a bit and love it (one of my favorite packages on pfsense.) Second- trying to suppress an internal IP (ie. 192.168.1.xxx). I do not have ANY + sign in the alerts tab to add it to the suppression list. As far as I understand, you can add NATted local IPs to the list right? Even when I modify the alias directly and reload, pfblocker continues to block the packets.

                                      For reference, I am blocking LAN outbound to certain countries and some on WAN too perhaps (not at the box to check.) But regardless, it just seems like my box is not working as it should. I'm running 2.3.1-p5 but I DID upgrade from 2.2.6 with pfblocker still installed (I stupidly didn't uninstall before the big upgrade.)

                                      Any ideas?

                                        You don't suppress Internal IPs.. Suppression is for External IPs and the Suppression Icon is only visible when "suppression" is enabled, and when the External IP is a /32 or /24. Also it won't suppress for Country Blocking…

                                        To have some internal IPs excluded from the Block Rules… Best to use the "Adv. Inbound/Outbound" Rule settings.

                                          Sounds good. Part of me thought that I'd have to adjust the rules and couldn't use the suppression but I figured I'd try.
                                          Thanks again mate.

                                            pfsense 2.2.6
                                            I use the country lists to pretty much block anything outside of US/CA
                                            I then have a whitelist set up for any exceptions
                                            I am pretty sure that in the past this worked fine.
                                            At some point the whitelist stopped having any effect.
                                            The firewall rules order also seems incorrect in that the whitelist follows the pfb block lists
                                            After poking around in the settings I found that setting the Rule Order to :
                                            pfB_Pass/Match|pfB_Block/Reject|pfSense_Pass/Match
                                            seems to get things working correctly - and the rules are now ordered as expected with the pass rule above the block rules.
                                            Did something change that requires using this rule order rather than the default to get whitelists to work ?
                                            I would have thought that this and the default would have been the same thing as far as whitelisting goes.
                                            Although this works I am concerned that this may have unforeseen consequences.
