[Modem] out of the blue PPPOE problem!

ok, my first post to dslreports.

i gotta tell ya, does everyone hate PPPOE as much as i do?

History:

My folks live near ft lauderdale in FL. They have ATT DSL service.

They have a motorola 2210-02-1022 modem and a dlink dir-601 (rev A1) router. The router is new (about 2 months)

They have been using a @bellsouth.net email address as their user id when doing PPPOE authentication.

I have them setup to have the modem in bridge mode and the router is doing the pppoe authentication. I do it this way cause I do a lot of port forwarding, and I dont think port forwarding works if modem does the pppoe authentication.

Everything has been going fine for the past month, until a few days ago when the router got stuck at "pppoe line connecting". So basically the stupid modem isn't giving the router an IP address.

i dont want to hard reset my router, as i dont want to go down that route yet. All my parents' clients can connect to the router with no issue, just the router can't get the IP address from the modem.

we did reset the modem, put pppoe authentication back on the modem, and connected a computer directly to the modem, and that worked. However when we then re-bridge the modem, and put the router back in the equation, we get stuck at "pppoe line connecting" again.

The settings on the router's WAN screen are:

Address mode: dynamic IP
re-connect mode: always on
MTU:1492

Any ideas?

Address mode: dynamic IP is WRONG.

It needs to be PPPoE.

sorry I will clarify:

Internet Connection Type: PPPoE (username/password)
PPPOE Internet Connection Type (address mode): Dynamic IP

This is in the DIR-601 menu:

Read thru all the recent posts in this forum. Others are having similar problems and it has been suggested that AT&T changed something in the PPPoE that is breaking some routers.

If so, it would not be the first time.

Here is one thread. No solution posted yet though.

If you use the public ip option that's on the motorola's connection configuration page and set the routers internet connection type to automatic port forwarding will work

wayjac,

thanks for the info. so to confirm, if i put PPPoE back on the modem and enable "use public IP address" in the modem GUI, i can do the following:

1. Port forwarding

2. DDNS, will the dynamic dns service that is built into the d-link router work?

Located here: »support.dlink.com/emulators/dir6···dns.html

Other than that are there any disadvantages I will have by leaving pppoe on the modem, rather than the router?

Will programs on my clients that use UPNP be able to open ports and work properly? just want to make sure that the modem has no firewall or port blocking capabilities (I just want my router to do that)

If you use the "use public IP address" setting in the modem, and use DHCP on your D-Link router's WAN interface (you may need to power cycle both the modem and the router to activate the setting), the modem will emulate being a dumb bridge modem and your D-Link router's WAN will appear to be directly connected to the Internet.

Whatever UPnP or other method you used when the D-Link router was doing the PPPoE authentication should still work exactly the same way. The biggest obstacle may be that your router is not compatible with the modem in this mode. I have found that occasionally a router will not work with an AT&T modem in IP passthrough mode just as some routers are not compatible with doing the PPPoE authentication with AT&T modems. For example, I was never able to get either my Linksys RV082 or my D-Link DI-LB604 routers to work with IP passthrough with any AT&T branded Motorola, Westell, or 2-Wire modem that I tried (the DI-LB604 would work with a Netopia 2241, but not with any other Motorola/Netopia model that I tried). Hopefully you will have better luck.

You may also want to contact your router vendor, or start watching their support forum if they have one.

If AT&T made a change that broke router PPPoE compatibility, the router vendor will hear about is very soon as you will not be alone in this. A router firmware upgrade usually becomes available soon.

With the modem doing the pppoe and also set to use the public ip
You can forward ports with the router
The router will have a public ip address and ddns will work

No, not with this setup

That depends on how well the routers upnp works

thanks for all your help guys, I used the public IP setting, and my dir-601 router works just dandy with ddns and port forwarding! yee-haw!!

maybe pppoe isn't so evil after all.....well...naaa i take it back, it still sucks when things get busted...at least my Crapcast here in santa clara doesn't need pppoe

Its not just "something" they changed the net password. For newer modem this can be done transparently remotely.... older ones like the Westell 6100's all come to a halt. And any modem that is bridged can't be done remotely either.

The password is no longer your old BS.net password.

Only solution call them up, and get it... though they seem to provide an automated way to do it, doesn't work.

I guess they have are doing this on a rolling basis, as there was a lot of this about a month ago... when happened to me and many others in very So FL... guess its in a new region now.

I just noticed OP's location... news to me California is in the SE.... but guess they are doing this nation wide region by region, and haven't yet learned to give customers advanced notice..

Actually the advance notice about the PPPoE/Network password change went out well over a year ago (along with instructions on how to change it yourself), but it was in an advertising email sent to the primary at&t/BellSouth email address for the account, and most people just ignore such emails (if their spam filter doesn't delete it automatically).

Clearly that has not the been case for many, who maybe like me just choose to use my own mail (or .web mail), and rarely check the functionally bad news BS mail... though I did not long ago at the PW change time here a few months ago. NO PW change notice email, but there was other at or over a year old.

This is DSL on my phone line....They KNOW the number...maybe leave an automated voice mail???? But NNNNOOOOOO.

I mean like the mailbot shouldn't know this is a totally inactive account but for rare incoming mail. Never even used enough to generate a SINGLE piece of spam

I have run my own email servers for my own domains for many years, but I also still check my ISP's email just to keep abreast of account and service notifications. But that is just me...I don't like surprises.

FWIW, most of the advertising style notices that I received from AT&T/BellSouth were actually flagged as spam by the AT&T/Yahoo! spam filters (probably because they contracted with a popular spam sender to send them). The default action for spam (as I recall) was to delete it after 30 days. An email that went into the AT&T/Yahoo! spam box over a year ago would have long ago been deleted.

What is this "notice" you speak of? Some of us don't check our @bellsouth.net email because it's been broken for years. (And I just don't give a ****.)

The notice was an email informing customers of the change in password policy that required a separate (different) primary email account password and and network (PPPoE) password. I checked my primary AT&T/BellSouth email accounts regularly when I has a DSL customer, primarily so that such changes did not take me (and any clients who were also AT&T customers) by surprise.

Sorry that your AT&T/BellSouth email is broken. Mine still works (both primary accounts and multiple secondary accounts) even though I am no longer an AT&T DSL customer (and I still use them for purposes where I don't wish to use one of my "real" email addresses). Perhaps they still work because I migrated my AT&T/BellSouth email accounts to the Yahoo! platform manually shortly after I received the notification that if I did not do it manually, AT&T would do it automatically (and we all know how well AT&T's automatic change processes work).

Oh. That. My network and email passwords have never been the same. Funny, back in the day, bell support minions thought I was crazy. It's been broken since they started farming around how to "do email" -- now they're just Yahoo! accounts (read: they cannot be bothered to run an email server. at least Yahoo! runs servers that usually work.)
