      I would also suggest you use ssh with password login disabled. Only pub-key auth…

      The you can tunnel port 443 into ssh and get your WI with https://localhost from your computer initiating the ssh session.

        I wouldn't recommend leaving ssh open to the world on the default port, either.

        Pub key auth is a must, as well as using non-standard ports. Something unlikely to be guessed or scanned, but in reality anything but port 22 is probably safer.

          But with pubkey enabled it is quite safe to use port 22…

            No reason to tempt fate there. :-)

              Thanks for all the feedback.  As a bandaid I locked it down to only me remote network for HTTPS.  I will also look into the other suggestions.  Thanks again.

                Instead of just allowing everyone to access the WebGui, restrict it to cretin IP ranges that you often use. This has proven good to me so far with SSH and WebGUI. I do this in case the VPN tunnel breaks, i still have a way in.

                The best way for normal access should be through a VPN.

                  Assuming pfsense is still using lighttpd as the webserver,  you can configure what ciphers it speaks.  http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs:SSL

                  If you look at the PCI DSS Compliance section that shows some higher security ciphers.  You can configure lighttpd to only use those.  This is of course besides the sensible advice above about restricting access to the web interface.  But should you ever see this issue on another lighttpd server you can see how to correct it :).

                    Tried setting up SSH Authorized Key but it does not seem to work.

                    I pasted the following from the Public Key File created using puttygen:

                    –-- BEGIN SSH2 PUBLIC KEY ----
                    Comment: "rsa-key-20100303"

                    GZ2FC1U=
                    ---- END SSH2 PUBLIC KEY ----

                    I was still able to connect via SSH without the need of any private key.  Also disable passord login for secure shell.  Still getting prompt for username password and able to login.

                      Try omitting the begin, end, and comment lines.

                            When I use the one with ssh-rsa I get connection refused.  When I go to auth in putty and select the private.pkk file and try to open the connection I get connection error.

                              Did you get your key by opening puttygen and loading your private key there?

                                I generate public key and copy then export private key. Right?

                                  You can use puttygen to generate a pair and then copy the key from the top of the window which says "Public key for pasting into OpenSSH authorized_keys file:"…

                                    Here is a new example:

                                    ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIBb5HVQf5Nbdu6+bC2dE2bM1ZNC/7USV/jJRcRNtBSu9plZCEAz4BRwCkMiuHlFNHT+FO6fjcdg9Jzb/csZ8SyVP9wY0iSDYeDd9eY5N04LceCGb2AxqrL24a09BftVSlQnXvbsPaume+fKgVVMo6NCDoUhPI917PUyIlNZ8YBD9w== rsa-key-20100303

                                    I pasted this into System:Advanced:Secure Shell:Authorized Keys.  Saved.

                                    Then open Putty and loaded session with internal pfsense IP.  Clicked on Auth in Putty and browsed to the Private.pkk file which I downloaded from puttygen.

                                    Fail.  ???

                                      Yep. That sounds about right. Are you running 1.2.3 also?

                                          Should I remove:  rsa-key-20100303 from the end of the key?

                                            Nope. I have that, too….

                                            Please check when logged in that the key is really there....

                                            cat .ssh/authorized_keys
