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. Russell Hurren Managing Director Zero Point Networks PTY LTD +61 8 6262 9376 On 11 May 2014 15:32, Mike Everest <mike@duxtel.com> wrote:
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.
