      Well, I replaced my nics with Intel ones and that was it….
      I needed stable system and Intel gave me that...

        @xbipin:

        cant we take the vr drivers from FreeBSD 10.x and test it on current pfsense to see if it will actually fix this issue

        Possible but might not be trivial: FreeBSD internal interfaces and data structures might have changed significantly requiring considerable work to backport those changes as well or rewrite the vr changes from FreeBSD 8.3 to 10.x to work in FreeBSD 8.3 context.

        Best case (assuming familiarity with FreeBSD kernel build procedures): maybe an hour or two to import the 10.x source into a 8.3 build system, recompile and run some basic tests.

        Worst case: maybe up to a few months to figure out what changes in FreeBSD internals to backport and do them.

          how about just check the drivers code and see the changes and cherry pick them which possibly might solve this network port stuck in a limbo state

            Given how widespread the Alix install base is - pleeease, no. No backporting of vr drivers from FreeBSD 10.x to 2.1. While I can understand that it sucks for affected people

            • this can apparently be extremely easily worked around by putting a switch between the pfsense box and the modem,
            • this clearly affects a tiny percentage of users with specific NIC/modem/DSLAM combo on PPPoE specifically.

            => certainly not worth the risk of breaking everyone else

              lets just leave it to the developers to decide, what they can do is provide the drivers separately to install so every1 dont need to use this

                I have this issue and it occurs more frequently since updating to 2.0.3-RELEASE (i386).

                I doubt a switch is going to make any difference in my case because I am running pfsense in a VM that effectively has an always up (virtual) switch, connected to a physical Intel E1000 card port patched straight into a routerboard (all gear on battery) so I am not getting disconnected because of a layer 1 issue.

                I'm a bit lost at how to proceed. Running a script to tear down the interface and bring it back up if it's up and experiencing no throughput (but it is present) seems like the best bet

                  thats the only way to get back the link going, if u read few posts back, some1 did design a script for this and it actually worked, atleast to some extend

                  y dont everyone add some amount to this so some1 can develop a fix for this, probably a newer driver might solve it

                    Thanks for the tip about the script. How can the bounty be added to apart from just making a note in my post?

                        I had similar issue with FreeBSD 9.1 RELEASE and pppoe('8'). The fix was to 'enable echo' in ppp.conf.

                        echo
                            Default: Disabled.  When this option is enabled, ppp will send
                            LCP ECHO requests to the peer at the frequency defined by
                            echoperiod''.  Note, LQR requests will supersede LCP ECHO     requests if enabled and negotiated.  See set lqrperiod'' below
                            for details.

                        Prior to ppp version 3.4.2, echo'' was considered enabled if     lqr was enabled and negotiated, otherwise it was considered dis-     abled.  For the same behaviour, it is now necessary to enable
                            lqr echo'' rather than just ``enable lqr''.

                          I am wondering if this thread is about fixing the issue that I have (excuse my ignorance, but this thread is quite long):

                          When I unplug the cable to my DSL modem (Alix, pfSense 2.1) and plug it back in, I cannot establish the pppoe connection again (a reboot will fix it, haven't tried anything else, sorry). If I disable the pppoe connection in pfSense prior to reconnecting the cable, I can establish the pppoe connection again.

                          We use the mighty pf, we cannot be fooled.

                              Ok coming back to this after some time.

                              I think i have solved the issue here and tomorrow snapshots should have a fix.
                              Can you test and let me know?

                                        This should work as before or better in 2.2-RC++

                                          well after the last changes u made the situation is same for me, if i unplug or modem goes down and up, then it wont connect at all in hours also, only way to make it connect is reboot.

                                            the system log does show the interface a down and then later a linkup message but it just wont reconnect and more interesting is y does the below fail

                                            bear in mind that FTTH modem the isp has given here, when u connect the wan cable coming out of it to any machine, by default it wont get any ip at all, in windows it would try and then fail and revert to 169.x.x.x, the machine would just say cable connected but no ip on it, not even any private ip
