PPPoE reconenction fix - mpd fix ($100)
-
will $200 be good to fix this?

im using the alix 2d3, the FTTH modem is by Zhone technologies (ZNID-GPON-2520), also tried with huawei DSL and cisco cable connection devices, the DSLAM is provided by unisphere for all the isp i had this issue with, pfsense is the nanobsd 1g 2nd feb 2013 snap
Well, could you check the very same setup with a different pfsense NIC (e.g. Intel) or running pfsense in a VM, to see if you can replicate the issue ?
But if it's some odd interaction between mpd and Unisphere DSLAM, I think your best bet would be the mpd developers …

the issue remains when trying windows dialup connection using a realtek nic to ftth modem by isp.
i have tried contacting mpd developers a few times recently also but no reply.
the only working fix as of now is bringing down the interface and then back up again and this was provided by wow a few pages back but it works in delayed fashion but probably some1 from pfsense can add this to pfsense in a more reliable manner so when pppoe disconnected, then kill mpd, bring down interface, wait few seconds, then bring back itnerface, wait few seconds and then launch mpd

After suffering from very similar logs and lots of googling I found a cure (well a cause) for me anyway.
If the router came up after pfSense (if it was powered off then on again), pfSense would not connect to it no matter what unless you power cycled it again or yanked the cable. What I found was happening was when the link first came up pfSense would grab the ip address from the router using DHCP and start sending its pppoe requests to it (producing the same logs about connecting posted earlier), it would never log in. Pulling the cable, waiting a bit then plugging it back in would then log in straight away.
What was happening was the first ip address it obtained from the router was a local 'admin' address (in my case 192.168.2.10), the router would then connect to whatever destination and sync, it would then change it's ip address to the correct WAN IP (In my case 217.155..), but as the link status stayed as 'up' pfSense would not grab the new ip address and keep sending it's pppoe junk to the original 192.168.2.10 address. No amount of ifconfig up/down would shift it.
The solution to my problem was just to disable the DHCP server in the router as it isn't required anyway (admin access can be got using a static ip). Now I can power on/off router or pull/reconnect cable and pfSense picks up the status and the correct ip address straight away with no rebooting or anything.
I hope this is of use to someone as googling this issue picks this post as the top one.
the above was posted by another user but he managed to login into his isp modem i guess but in my case i cant do that, its not giving me access in anyway nor is dhcp enabled on the modem so i dont suffer that issue

it would be helpful if some1 could get me a proper mpd developer contact

I am having this same problem. I am going to purchase another device to mange my ppp connection and pass that interface forward.

sooner or later more ppl will have this issue once isp switch to unisphere BRAS or they upgrade its software or they implement one session per id restrictions
bytheway i have posted this on mpd forum as well but just one reply where i was asked for logs
http://sourceforge.net/projects/mpd/forums/forum/44692/topic/6720934 -
there was some progress on this matter with the mpd developers and one way they showed to delay sending the PADT when modem is down was by setting set link keep-alive to a higher number and i did that and before mpd could renegotiate a new connection that modem came up but still the connection wouldn't continue and this gives me a strong feeling its the interface drivers but for time being still coordinating with mpd developers
-
the other ppl having this issue or had this issue in the past, can u confirm ur using a alix box as well?
-
Its not an mpd issue it is a netgraph issue.
I told you that my priorities are set and will come back to this when i can.For the mpd developers tell them that seems ng_ether has this issues with attaching/detaching interfaces or ng_iface.
Though there are some patches specifc to pfSense that might be needed to be tested as well. -
ok fine, no1 was replying so i thought it was forgotten completely.
bytheway few suggestions on the mpd forum helped a bit,regarding PADT packet which used to be sent when modem was down so they said to increase set link keep-alive value and so i did but if alix was connected to modem directly it wouldnt help but if connected through a switch then mpd would continue connection once modem was up again and i also tried setting the standard value of 60 for it and in that case also it would connect but after some time and had to goto interface and hit connect in which case mpd was killed and a fresh instance started. i have generated log for both and will keep with me till required.
meanwhile ill reply on mpd forum about it not being a mpd issue
-
bytheway mpd developers replied this
And what those pfSense-specific patches are? I personally run mpd as PPPoE client using stock FreeBSD 8.3-STABLE and vr1 interface at home and have no netgraph-related problems with it
-
they mentioned this as well
Ethernet card driver vr(4) is known to have major problems with traffic restoration after physical link down/up. This problem have nothing to do with mpd/netgraph. You need to contact FreeBSD developers or replace your hardware to get other type of NIC. Also, read this:

How I fixed it:
Changed my USB Ethernet adapter for a different chipset, PCI Ethernet adapter. Voila!Zentyal, ClearOS and even pfSense failed to reconnect while using a Linksys USB200M, but I've had this same problem using another USB adapter (Intellinet, different chipset… I don't remember which). Maybe it's tied to USB adapters?

I just installed pfsense (2.1-BETA1-4g-i386-nanobsd-20130507-1652.img.gz) on my Alix2d3 and I'm experiencing the same issue. Any news on a fix or workaround?
-
Ummm OK, here is my experience…
Yesterday my box crashed and burned :) So I build a new one from an old PC...It has 2 NICs. 1 realtek (vr0) and one Intel (em0).
Now, if WAN is on Realtek card it will never reconnect. But if on Intel card (em0) it will reconnect with no problem at all...
Before that I had 4 Intel 100 cards (fxp). It also worked like a charm.So my suggestion for pppoe user is, use Intel NIC for WAN and you should be just fine.
I do believe this is NOT mpd bug but driver bug.My 2 cents…
-
so considering a driver bug, how much would it cost to fix it or do the drivers need to be fixed from chipset manufacturer or freebsd?
-
Considering the multitude of Alix boards here not having any such problem, cannot see how's this a generic Realtek issue.

Don't Alix boards have VIA NICs (not Realtek)?
-
yes they use VIA and im desperately ready to pay to get this fixed
