          What does the 11th one do? System log, PPP log, anything else relevant you're seeing.

            I am interested in this topic.

            Where is this failing? On creating the 11th PPP interface or when adding the 11th PPP interface to OPT interfaces?

              3G modems used: Huawei E1550

              I don't see any errors on General/PPP log. The modem is detected normally just like the rest of the 10 3G modems. The only problem is on PPPs Configuration>Link Interfaces. The 11th link interface does not appear. Attached is a photo of PPPs configuration.

              General log upon inserting the 11th modem

                could you post the result of this:

                
ls -alh /dev/cua*

                try this with and without the 10th dongle in place…. this would atleast show if the "dailer-device' gets added to the system

                  I expect the problem is in /usr/local/www/interfaces_ppps_edit.php
                  https://github.com/pfsense/pfsense/pull/1752
                  That pull request is against master, but you can try to see if it fixes it by:
                  Diagnostics->Edit file
                  /usr/local/www/interfaces_ppps_edit.php and Load
                  Search for "glob"
                  The glob expresion "/dev/cua?[0-9]{,.[0-9]}" - remove the dot so it is just "/dev/cua?[0-9]{,[0-9]}"
                  Save

                  That should allow cuau0 cuau1 cuau2 … cuau10 cuau11 ... cuau99 devices to be matched. Then you can have 100 3G modems :)

                    Thanks Phil. Merged that to master and RELENG_2_2.

                    rowell: next 2.2.4 snapshot @ https://snapshots.pfsense.org past the date of this post (probably the first with a July 15th date) will have that fix, please test and report back.

                    Now how long until someone comes and posts they can't use more than 100 3G modems? :) I'd say 100 is more than enough.

                        We will see - it just occurred to me that the change I made will now not match device names like /dev/cuau1.1 - which it would have matched before. I made a comment on the commit and @cmb and @jimp will know if device names in that format actually exist and need matching.

                          The finalised version of this was committed a few days ago.
                          @rowell - can you try https://github.com/pfsense/pfsense/blob/RELENG_2_2/usr/local/www/interfaces_ppps_edit.php (that is the version to be released in 2.2.4)
                          Does that fix the issue?
