Hi Paul I just tried connecting from Windows PPPoE client through the Mikrotik to WebVault, and that worked fine (both using dynamic and static IP). If I don't specify an IP, they'll allocate one automatically, but it won't be the static IP (they said they were working on the issue). It's a private IP, and I only need it to be static because of some tunnels between this and other routers. I've tried using the default PPP profile, and my modified one that was a copy of that, just with the static IP. PCI and VPI are definitely correct, and I'm using LLC. On the Mikrotik, the PPPoE interface says 'establishing link' but that's as far as it gets. I've attached the output of '/log print detail where topics~"pppoe" (with my password obscured). Note that I've also got an active connection to Telstra (which is working fine). I've tried all kinds of different settings with MTU/MRU, I've also tried disabling everything except CHAP (on WebVault's suggestion), as well as leaving all protocols enabled. One more thing I'd like to try is using a Linux PPPoE client (particularly if I can use the same one the Mikrotik is using). I don't have a linux box handy though, so that might have to wait until I've got some time.

That doesn't make a great deal of sense to me, every ISP that I know of allocates static IP's from radius, including ourselves, that's just weird saying to set the IP manually on an ADSL WAN interface.
Does it get to the point where the PPPOE Interface says it's connected at any stage Russell ?
If you plug your PC into the ADSL modem can you create a PPPOE interface on your PC (assuming windows) and connect successfully doing that ? That test will confirm that your modem is working right, other things to make sure of are you have your VCI and VPI set correctly, 8/35 is it's a resold Telstra service or most others, also ensure encapsulation is set to LLC not VC Mux, and see if you can connect with your PC.
If your PC works fine like that then there is no reason the Mikrotik won't, it's no different, also make sure you are selecting the "default" PPP profile and not "default encryption"

Thanks Mike
Here's James' (WebVault) reply
I don’t know enough about L2TP to comment, our LNP server receives
connections from a LAC aggregator from the carriers network, which is fairly normal I guess, but I cant comment on how that works either. You should set your IP Address manually on your PPP interface dialers if you want it to be a static address.
Another client had a PFSENSE product, and had this to say about negotiating the IP, I don’t know if it helps:-
I don't know what's different about the way the IP address is being negotiated from when you gave me the static internal IP, but the config on PFSense had to change from negotiating the IP during PPP to negotiating after the PPP session was up. Makes no sense at all to me but now I'll know for future.
I can try again tonight (don't want to drop the internet during the day) and capture the log and go from there.

Hi Russell,
I have never heard of the issue described in that forum post. Also, with only 13 posts to this topic over almost 4 years, I don't think it is a terribly common problem :-}
The bottom line is that a true transparent bridge all the way from routers Ethernet port all the way to pppoe server is required to make it work properly. There are 2 general rules:
1) avoid half bridge or psuedobridge modes and only use a modem that supports a REAL transparent bridge mode 2) watch out for MTU problems - many modems break MTU discovery (and many LNS implementations break it too!) so change of MSS is often required
I suspect that the webvault service may have additional tunnel or vlan on the access network which possibly pares off more overhead to reduce the maximum frame length further than 1482.
Have you contacted webvault support regarding this problem?
If you still suspect a pppoe problem, please capture some packets showing pppoe failures, and then we can try getting a case open with MT support - if it really IS a routerOS bug, then we should be able to get some attention and have it addressed eventually ;-)
Cheers, Mike.

Hi Paul
I've tried just about every setting I could find on the Draytek. In the end I got Telstra working by putting it in MPoA 1483 Bridged IP LLC. When I do the same thing with WebVault I can see the PPPoE server when I do a scan from the Mikrotik, but I can't connect. The Draytek itself can connect using it's PPPoE client, and it has to be PPPoE mode, not PPPoA.
I still suspect it might be something to do with the problem described on this thread: http://forum.mikrotik.com/viewtopic.php?f=2&t=46384
Basically the routeros system looks to have an issue with any pppoe system
terminated against a LAC, and when the session is forwarded to the LNS for authentication the router os sees the new host uniq for the LNS and drops the session. This appears to be an issue with the router os implementation of PPPoe, I have read another few forum posts which confirm a similar situation. I cannot debug this any further, firmware changes from old to new dont make a difference and it is definitely not a hardware fault (happening on multiple different devices). We have for the time being made the pppoe session terminate against a linksys router which works fine.
Regards
Russell

Russell, maybe they use pppoa ? Is that possible ?

Thanks everyone for your replies. I was able to get the combination of Mikrotik + Draytek bridge + Telstra Bigpond working (had to fiddle a bit
turns out I hadn't put it in bridge mode properly). I'd already played around with the MTU/MSS settings and had to undo some of what I'd setup for the half-bridge to get it to work.
I'm still having the same problem connecting to WebVault though. I tried using a TP-Link bridge instead of a Draytek and had the same problem. I can ask WebVault if there's anything peculiar about their setup. I can see a whole lot of stuff in the logs, but not sure how much is
relevant.
is a small ISP, so they use other carriers (eg AAPT) for ADSL.
My immediate problem is solved though - I wanted to connect one of my clients to Bigpond using PPPoE to eliminate the possibility of half-bridge mode causing problems with his VPNs. If I have to use half-bridge for WebVault I can live with that.

Is anyone successfully using the PPPoE client on a Mikrotik router with an ADSL bridge? I'm using Draytek Vigor 120 routers and I'm having to run
WebVault them
in half-bridge mode and terminate the PPPoE connection on the device rather than on the Mikrotik router. In the past I've been able to connect to Telstra Bigpond from the Mikrotik, but I'm not able to anymore and I've never been able to connect to my primary ISP (WebVault). I've used the same draytek devices in full bridge mode with other brand routers making the PPPoE connection, so I'm fairly sure the issue is with the Mikrotik PPPoE client.
I'd be interested to hear what ISP and hardware you're using if you've got this to work. I've contacted Mikrotik support and found a similar issue in the forum (http://forum.mikrotik.com/viewtopic.php?f=2&t=46384), but no-one's answering me.
