      Just trying TTL 2147483647 which will generate its own operational signature.

      https://www.ietf.org/rfc/rfc2181.txt Section 8 TTL.

            Actually anything not running DNSSEC is vulnerable to this attack:

            1st Man on the side attack where you someone listening passively on the side does packet injection and spoofs a DNS response faster than the real DNS server.  They send you to their fake server loaded with forged certs and forged websites that look like the real thing.  (Thats the really evil version) or perhaps they just redirect you to some BS crap shopping site.

            2nd Once your server connects to theirs they fake the website you were trying to visit and complete the HTTPS transaction and forward you on to the real site - via their server.  Now they are the man in the middle and can read your supposedly encrypted traffic, inject packets inject malware, whatever.

            So, thats pretty much 99% of the web users are vulnerable.

            IMHO pfsense doesn't sell its self hard enough on its security features.  Not in terms average buyers can grasp anyway.

              Wonder if that was the case with this one: https://forum.pfsense.org/index.php?topic=87491.0

                  Ok, i made some screen shoots of the settings i have now.

                  @kejianshi
                  I'm still not sure about the gateway.
                  You said pointing to the modem is how grandmother did it: https://forum.pfsense.org/index.php?topic=87678.msg483085#msg483085
                  But then you said: "Don't mess with the gateways".

                  And to make sure i get it right: With this settings i get name resolving directly from the 13 Root-Nameservers (Anycast aside)?
                  If thats the case then why everywhere are this alternative DNS server lists and why is this not the default in routers from ISPs?

                  I guess i change the title of this thread - maybe it helps others.

                    Name servers that return a bullshit IP address instead of NXDOMAIN for A records that don't exist are an abomination.

                    I will be switching over to a resolver-based configuration this weekend now that I'm on 2.2.

                    DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

                      well your resolver is on all all, which is not how I would set it up.

                      Resolver should only listen on your lan port, and should only talk to other dns on your wan.

                      And don't see how you expect pfsense to resolve anything - so its not going to be able to check for updates..

                        You could deselect WAN without hurting anything or you could just not open port 53 on WAN…  Either way.  (P.S. Its not open) 
                        It should work and resolve just fine the way you have it here.

                        Easy way to check if your system is resolving and if you can get updates is to go to the main pfsense gui and see if it show "you are on current version"

                        If it does, your pfsense is resolving fine for its self and probably for all the other machines on the LAN.

                        Now, go to https://www.dnsleaktest.com/ and see how many resolvers show up.

                        Hopefully its like...1

                          Selecting just LAN on "Network Interfaces" and "Outgoing Network Interfaces" gives the error:
                          This system is configured to use the DNS Resolver as its DNS server, so Localhost or All must be selected in Network Interfaces.

                            Select all.  Port 53 is closed on the WAN.  No issues there.

                                Then select both lan and localhost ;)  ALL is BAD practice!!

                                  I wouldn't screw with the gateway…  unless you are in the mood to upgrade to a ISP/Modem combo that gets you a public IP on the pfsense wan?

                                    Not sure if you know, but you select individual interfaces by holding the cntl key while clicking on the ones you want.

                                    What johnpoz is saying is best - I was trying to keep it simple…

                                      I know that :-) - My computer knowledge is good but pfSense is overwhelming :-)

                                      So the important part here is that on "Network Interfaces" you just have the internal and
                                      on "Outgoing Network Interfaces" the external stuff?

                                      Gateway:
                                      I did check my ISP router and i have the bridge option now.
                                      I made the hack a year ago and the option was not there - seems like after
                                      some firmware update it changed.
                                      I have a warning "from manufacture not supported change".

                                      So i can select LAN2 as bridged.
                                      But if i do that and connect my pfSense WAN NIC to LAN2 i can not reach the router anymore with 10.0.0.1.

                                      What changes do i need to make in pfSense to test it?
                                      I guess in "Interfaces > WAN" and "System > Routing > Gateways"

                                          Wait.  If you select bridged your router is no longer a router so you might not be able to get to it any more at all and, frankly, who cares?

                                            I care cause the phone book, caller list, fax stuff and everything is handled by that box.
                                            There are two phones connected to that box. You can't use dedicated VoIP phones with german
                                            cable ISPs (VoC) cause they don't work. They don't give you the access data and it only works from
                                            your box in your house (not like normal VoIP).
