      there is a PC on my network that has a hard coded domain name in the hostname field used to connect out to a security camera server on the internet.  the hostname is no longer valid (it was a free dns updater service).  the service has expired and the name is no longer valid, but the program defaults to that every time it is launched (due to how it was installed).  i can manually type the new hostname (another free provider) and i can connect, but as i said, it defaults to the old name.

      is there a place in pfsense that will allow me to configure something like this:

      oldhostname.freedns.com –------> newhostname.2ndfreedns.com

      thanks.

        If your device uses pfSense as its DNS server, simply entry a host override under Services > DNS Forwarder.

        You can make any hostname resolve to any IP you want there.

            Make a host override in DNS forwarder > then just fill in a domain alias for that host. Doesn't have to be an IP. It works on my system.

              The following input errors were detected:

              The field 'IP address' is required.

              not letting me proceed w/o an IP

              the domain is not the same

              oldhost.domaina.com

              newhost.domainb.com

              i need to set it up so that anytime oldhost.domaina.com is requested, pfsense redirects it to newhost.domainb.com

                  i am on:

                  2.1-RC1 (i386)
                  built on Sun Aug 18 19:11:13 EDT 2013
                  FreeBSD 8.3-RELEASE-p9

                  You are on the latest version.

                  post a screen shot of how i should be setting it up, if you dont mind.

                  i dont need an IP address, but i cant save the changes w/o one, i am not sure how you are getting around that.

                  thanks.

                    Maybe I discovered a feature. I am using Split DNS to point the domain name to an internal host. I left hostname blank.

                      unfortunately, that is not what i am trying to do.

                      i am trying to redirect a hostname to another hostname.

                      not hostname to IP.

                        Ok, that's what I did whit the alias. Can't you use that function? You can use the hard coded hostname and the IP address and then make an alias, can't you?

                          i need the IP field blank, unless i am missing something.

                            I did read again your first post and I now see I don't understand you. You said that you could connect with the new hostname, but then it defaults to the old hostname. What does that mean, or what do you see? Is it just a cosmetic thing?

                              i have a computer that use to connect to oldhostname.domaina.com

                              the program defaults to that hostname since it was the one used when the program was initially setup.

                              in the recent days, i have a need to use a new hostname, newhostname.domainb.com

                              what i am looking to do is create an alias for the old hostname to point to the new host name so that when the computer is requesting the name oldhostname.domaina.com pfsense picks that up and redirects to newhostname.domainb.com

                              i can fix this issue by reinstalling the software and using the correct hostname (this is a flaw of the program), i was just hoping i could do something at the pfsense level.

                              thanks for your help, it is appreciated.

                                I cannot see how's a program expecting oldhostname.domaina.com going to respond to requests to newhostname.domainb.com.

                                  the program wont.  when it looks to pfsense to connect out via the internet, pfsense will redirect it.  basically, i'd like to enter a cname into pfsense.

                                    I have no idea what "program" are we talking about here. If you expect that pfsense DNS record will rewrite e.g. www.google.com to www.bing.com in your browser URL bar, then it's not what's gonna happen.

                                      on the client side (the program) it will use the original domain old.domaina.com

                                      it is a cname, have you ever worked with cnames?  that is what i am looking to do.

                                        Your CNAME will not work if the program somehow works with the requested hostname. Once again, see example above… It won't work either if we are talking about some IP camera with a webserver.

                                          it works all the time in the scenarios where i am hosting my own domain and i can create a cname.  it doesn't seem that i can do that in pfsense.

                                            Well, that's awesome. How about reinstalling the broken thing instead of inventing similar nonsense like hijacking nonexistant hostname with a DNS forwarder?
