PPPoE and PPPoA

I live in the UK, over here we use BTBroadband ADSL that uses PPPoA, now as many useful Routers use PPPoE is there some sort of ADSL modem that will dial a PPPoA wan connection but that will provide a PPPoE connection to a router so I could use PPPoE routers.

Thanks

This is exactly my problem. My freeserve ADSL is PPPoA, so my modem dials up to it ok (luckily it supports it) but when I come to use my Firewall/Router it can only connect to PPPoE, so if I try to connect through the router I get a message saying 'could not find a PPPoE server'. I was hpoing to find a firmware update to give it support for PPPoA but no luck. It looks like ill just ave to go without for the moment.

Thats the ADSL Modem I have, and no it doesnt provide PPPoE, only PPPoA if you connect in the UK (it doesnt work with the router I have). The router is a linksys BEFSX41 router with firewall. If I enter the setup and config through IE it has a list of connection methods - PPPoA isnt in there and if I attempt to connect through PPPoE it says 'Cannot find a PPPoE server'.

You sure?

"Embedded PPPoA, PPPoE, IPoA clients " or so the spec says. Maybe worth checking out any hidden settings. Bear in mind that in the UK you don't need PPPoE, so why worry.

It supports PPPoA, but it outputs PPPoA. I think the original person wanted it to support PPPoA, but to output PPPoE (if this works?). ooo Im confused.
Anyway, if Ive got that modem, do I need an entire DSL Roter to split the connection or can I just use a switch/hub. The modem that ive got (the one you linked to) was classed as a single-port router so I was hoping that I wouldnt need a router but just a hub or a switch to share my connection. Am I right?

A hub will split the connection from PC to PC and the bandwidth will be shared. A switch will allow (assuming it's the right spec) 10/100 PC to PC data transfer over as many PCs as you have ports, but still you split the bandwidth from the outside world as the PCs call on it.

Personally I went for a 4-port router with a built in 10/100 switch and modem. Covers all possibilities. The cost of a hub or switch versus the cost of a router minus the cash you may get for your modem may make it worthwhile.

For a basic grounding on networking terms try any networking FAQ you can find. <A HREF="http://forums.btvillarin.com/viewtopic.php?t=301" target="_new">Here's</A> one. :wink:

I also recommend you contact your ISP or your phone compant to find out which standards and requirements your network devices should possess. For example in the UK you should look for:

Encapsulation: PPPoA (RFC-2364)
Modulation: G.DMT or ANSI T1.413
Authentication: CHAP

and so on.

Ahh, You're in the UK, so that much is easy. Don't forget...

VPI=0
VCI=38

If you have a single IP address, be it static or dynamic, you will need to have NAT enabled. If you have a range of IPs they will be static and you may want to disable NAT for allocating IPs to particular PCs.
