PPPoE working on PC, not on router

My setup:

Siemens Gigaset SX762 acts as ADSL modem. Static IP -> 10.0.0.1
Linked to the Gigaset's Eth1, an Linksys WRT54G2 (WAN port), DHCP server

Problem:
Any PC connected to the Linksys can create a PPPoE connection.
Any PC on 10.0.0.x on the Siemens can create a PPPoE connection.
Neither the Siemens nor the Linksys manages to create a PPPoE connection.

I would really like to have either the Linksys or the Siemens create the PPPoE connection, as my Nokia 5800 can't do PPPoE, and neither can my Kindle.

I've used the Linksys in exactly this role before, on a little (now broken) D-Link modem. It worked perfectly then.

Any suggestions?
 
The Gigaset complains that Negotiation failed.
Can't see what the linksys worries about.
 
Unplug everything. Then connect Linksys WRT54G2 to the phone line and one pc via cable preferable. Leave the Siemens unplugged for now. Lets get one working. Log onto the Linksys and set up the Internet connection on it. Then in windows make sure that your default gateway is exactly the same as the IP you used to log into the router. Also double check that the router has DHCP server enabled. Let me know what happens after that.
 
^ do that ^

Possibility exists that you might have two active PPPoE devices on the network.

Best to cut it down to only one device and troubleshoot things from there.
 
My guess is that you haven't set VPI/VCI to 8/35, respectively, when trying to dial PPPoE connections from the Siemens router. That is the only explanation that I can think of.
 
First things first, I've currently got PCs connected to both routers (static IPs, 10.0.0.x range for the Gigaset, DHCP on the Linksys), and all are connected to the internet via PPPoE. All PPPoE connections are made on the PCs.

Secondly, the Linksys is a pure router, it doesn't have an ADSL modem. It's perfect if you have a broadband modem without a router, but it has no build-in modem.

Thirdly, the VPI/VCI is 8/35, with MTU of 1492. I've tried automatic as well, it simply returns 1492.

Thanks for the trying, but thus far I've thought of all the suggestions. I've actually started off with only the Gigaset, as I prefer one device. Since I can't manage to convince it to do a PPPoE I added the Linksys, which I knew work. My personal suspicion is that the Gigaset is to blame somehow. Just can't think how.

Sorry, double reply. I do have multiple PPPoE devices (1 PC, 2 laptops, 1 netbook) running at the moment. The linksys is also trying its best to connect. Telkom ISP, so multiple connections are allowed. I've also thought of multiple connections causing problems, and have tried cutting down to 1, and then 2 (just routers, PCs disconnected), but that doesn't solve it either.
 
On the router you are changing the protocol right? It should drop all the pc pppoe connects when you set it up on the router..
 
The linksys is acting as a half-bridge, meaning that it should allow pppoe connections through (it does, that part is working fine), and that it should create a pppoe connection itself as well. The siemens is connected as a bridge, which means that it shouldn't try to connect itself, but it should allow pppoe connections through. That it also does.

I have multiple ISP accounts, which means that I want half-bridges. It makes life so much easier if you can create an PPPoE pipe over your router, thereby bypassing the ISP PPPoE connection that you configured on the router itself.
 
O ok yes I had a similar set up when I had local and int accounts. Was just checking there weren't any conflicts as you never went off line. Without just fiddling I can't think of anything that could be causing this. My only suggestion now would be to delete every connect you have unplug everything and start from basic with one router one pc and pppoe no bridging and try get that to work. Maybe phone telkom and get there help. If you get through to a helpful person they are helpful contrary to popular belief..

Good luck!
 
I have a similiar setup, with my linksys setup as dhcp server and its WAN port connected to modem ETH1 port.

My settings in my WRT54GL (running dd-wrt)

WAN Connection Type
----------------------------
Connection Type: PPPoE
User Name: xxx
Password: ***
Service Name: MWeb
PPP Compression: Disable
T-Home VDSL 7 Vlan Tagging: Disable
Force reconnect: Disable
STP: Enable

MTU: 1492

My modem settings (telkom mega):

Bridged Connection Setup
--------------------------------
Type: Bridge
Encapsulation: LLC
PVC: 8:35
VPI: 8
VCI: 35

Hope it helps.

How do you setup the linksys as halfbridge (on a pure router)? I am also using multiple accounts, but had to do a custom job to be able to get it right.
 
Thanks all. I suspect that the fault might not be configuration, but something on the Siemens. I'll try another Siemens this weekend, see if that one works. Fortunately I have access to another one.

All that was suggested here makes sense, but I'm starting to suspect hardware or firmware rather than configs.

I could never get it setup as anything else! Mine acts as half bridge as I bought it - tries to create PPPoE through the WAN port (Ethernet), and allowing PPPoE connections through as well.
 
The DD-WRT firmware removes the half-bridge capability when installing it on the Linksys WRT54GL.
There's a workaround for that though, but then you basically lose 2 of the 5 LAN ports on the Linksys router! Instead of simply connecting the Linksys WAN -> ADSL LAN, you connect Linksys WAN -> Linksys LAN + you connect another Linksys LAN to ADSL LAN.
That way you can dial connections from the Linksys + allow other devices to dial PPPoE connections :) I think Gatecrasher told me that trick.

I'm really not fond of the Siemens Gigaset router. I've had endless problems with it, especially with accessing its web interface from the Internet and it's DNS + DynDNS settings.

Thanks. This is more or less the same workaround I am using :D (I run 2 cables between linksys and modem). But this worries me a bit, as your WAN is now connected to your LAN. So I usually only plug in second cable when needed.
