Pppoe acces concentrator on 'local' network, dual wan, single nic.

I live in a student 'dorm', and they have a quite difficult network setup here.
a gigabit (or something) fiber to the university, connected to a 'neighbourhood' lan in the appartment building. you get a 172.20.y.z adress and dns from the local dhcp, and on the same network, you 'dial in' to the pppoe acces concentrator that connects to the outside world, limiting internet acces to 1 computer per student trough the pppoe. the only workaround is a router that supports this particular kind of dual wan. This is where pfsense would come in, ofcourse.

where a windows pc would see a network, and after setting up "broadband pppoe" it sees a second (virtual) network connection with internet acces, no dns (so apparently the 172 dns does internet dns as well)

anyway, I'd like to connect more then once pc, seeing as I have 4 in my apptmnt, so I need a router, and there the problem starts.

If I set up dhcp client on the wan side, I get a 172.20.xx.xx adress, and then I can see the internal forum and such, but no internet.
If I set up pppoe, fill in my user/pass, I get a 145.xx.xx.xx public adress, but no dns, manually filling in the dns of opendns.org fixes this, and then I have internet, but no acces to the internal network. setting the network dns just results in no awnser, can't ping the internal network.

So, what I want is pfSense to connect to the network, and pppoe, so I have acces to both networks, over this one hardware lan connector sticking from the wall, but I can't figure it out. Googling and searching the forums gave some info, but I cant use vlans, nor does ip alias work (because it tries to find the 172 ip on the internet, perhaps the other way around, I have no idea how to run the pppoe client outside from the main wan settings page)

hardware:
Fujitsu-Siemens pentium 3 box with 192mb ram, 2 realtek 100/100 network cards, 15 gig hdd, cheap gigabit switch on the local lan side, pfSense version 1.2.3-RELEASE.

If I'm missing any details, I'll try to post those as well, oh, and to add, I know nothing about bsd, so if I have to do something in the terminal, please be specific about the commands.

I hope someone here can point me in the right direction, and thanks in advance :)

You can do this in 2.0. The PPPoE interface is not done on WAN directly, but a virtual PPPoE interface. This leaves the physical WAN free to be assigned and used at the same time.

;D that would be great, downloading and burning now, lets see :)

[update:] and its broken. updated to latest beta, and even after a 'factory reset', I can't get connection with either the pppoe internet, or the 172 'wan' anyway, I'm tired, I'll try again tomorrow. :)
