      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?

                                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

                                  Jan 13 10:20:55 	ppp: [wan] IFACE: Delete route 0.0.0.0/0 2.48.4.1 failed: No such process

                                  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

                                    I am interested on your system log not your ppp logs.

                                        From what i see seems mpd does not exit and the new instance is started.
                                        Probably need modification to kill the first the run the other one.
