I'm sure I'm not the most knowledgeable on this, but since I haven't seen anyone else reply, here goes: DSL providers will give you a DSL router, which sometimes is an internal PCI expansion card and sometimes an external box. Unless your ISP has written drivers for an internal DSL card to work with FreeBSD, you want the external box. (Otherwise, you may be forced to run Windows 98.) Likely, your ISP will give you only 1 IP address, so if you're going to squeeze multiple boxes through this connection, you'll have to perform IP masquerading of some sort. Your DSL router may be able to handle this, your FreeBSD can certainly handle this (and it's more fun that way), but the topology changes depending on which way you go: for the former, yes, you can just plug the DSL router into the hub with the rest of your boxes. For FreeBSD to handle the IP masquerading, you'll need to install another NIC in your BSD box, plug one into the local LAN, plug the other into the DSL router via crossover cable (or use another hub if you have an extra lying about). Additionally, unless I'm totally off my rocker, I don't think you'll need PPPoE for this. If you can provide some more detail about your topology, folks on the list can help you with the specifics if you get snagged.
