all the pfsense nanobsd v2+ have one pppoe reconnection issue related to the newer mpd being used and i desperately need a fix for it, this has been talked over and over again and again but most of the ppl out there dont have this issue but there r a few including me who face this.

mpd, pppoe etc logs have been provided but hasn't yet yielded anything and mostly the culprit is mpd itself coz the older pfsense and older mpd used to work flawless and used to reconnect perfectly even with cable unplug or isp router fail etc.

the issue is as follows:
on pfsense reboot, pppoe connects fine and everything working. once u unplug the cable between the isp router and pfsense then connection drops but as soon as replug it, it resumes fine, myb because the isp modem still remains in its configured state. now if u reset or switch off the isp modem then again pppoe connection drops but as soon as the isp modem is up again, pppoe goes in a infinite reconnection loop and wont reconnect till u reboot pfsense, what i think is when the isp modem is rebooted, it keeps its network port is some sort of state which just keeps pppoe in the reconnection loop or there is some if and else in mpd coding which detects different states and accordingly attempts a reconenct which while rebooting is different and while reconnection is different.

more ppl as me might almost contribute to this but bear in mind, the logs dont yield much so some more advanced debug method is required, i can provide access to my PC and box using dialup connection which some1 can login into it and try to see what happens behind the scene with mpd when such a scenario is recreated

one thing i forgot to mention is my dialup connection etc also run on that fibre optic modem provided by the isp/telephone company so even if i connect using dialup and replicate the issue by turning off the isp modem then my dialup connection would also die and u would loose connection.
let me try to find some other way to be connected to the internet and still be able to give ua ccess and replicate the issue.

access to my pc and the firewall i can provide using radmin or teamviewer etc

The logs displayed a couple of replies back suggest the remote PPP is not responding. Since this seems to be fairly easily reproduced I suggests you make it happen while you have a packet trace running so you can see if there is response from the ISP. Is there any response from the ISP's end? If not, call their technical support to report the problem.

command run with interface as pppoe0 and replicated a isp modem reset and complete endless loop for a while for pf reconnection attempt
file name - pcap.capture1

command run with interface as vr1 and replicated a isp modem reset and complete endless loop for a while for pf reconnection attempt
file name - pcap.capture2

the cable from the isp modem to pf if i put in my PC then the LAN status always shows limited connectivity and no IP from DHCP untill a pppoe connection is dialed out

all standard routers such as dlink, aztec etc sold in this region work fine when u replicate the same situation so i wonder how do they reconnect fine even if u reset or unplug and replug the isp modem

the strange thing is, suppose i remove the wan cable going from my isp modem to pfsense and reboot pfsense then once its done it doesnt have any internet connection and no wan ip but as soon as i plug the cable from my isp modem to pfsense, in just one attempt it connects and remains connected.

so i guess the issue is mpd would need the vr1 used for wan to do down and then replugging it would get it up and then mpd would dial out perfectly fine but if the isp modem was just reset then the port has the power on so i guess it doesn't go down completely and then reconnection attempt keeps failing. i mayb wrong on the above but at least on a pfsense reboot everything works fine and even on a cable unplug and replug also works fine but on a modem reset only it doesn't work or mayb if the isp modem hanged or dropped the connection then also it would connect but i havent been able to do that.
