Re: BSD PPPoA Hardware
Currently using a zoom x4 modem in half bridge mode with 3.6 stable and haven't had any problems with dhclient obtaining a lease from the modem so maybe it's a 3.7 thing?. I'm just about to move to 3.7 current so this is worthwhile knowing. Many thanks.

Hi Simon and others: I am using an Actiontec model GT701R DSL modem for PPPoA here on OpenBSD 3.6. It was easy to configure. The Modem itself has the address of 192.168.0.1 and does the Network Address Translation. First, I did: /usr/bin/sudo ifconfig bge0 inet 192.168.0.5 netmask 255.255.255.0 then /usr/bin/sudo route add default 192.168.0.1 Afterwards, I configured it with Firefox. Lynx or Links would not work. The DSL modem and PPPoA works like a charm. -- Kind regards, Jonathan

Shane I had no success with a Netcomm NB1300 either. I gave up debugging it but I can tell you that it drives the dhclient mad on OpenBSD because it only issues 60 second leases which results in 30 second renewal requests. Yeccc! I have a swag of client sites where I set the modem up to PPPoALLC , NAT on, DMZ Host = 192.168.1.2 (the static IP for the firewall and then it works just as well with all traffic to the WAN IP hitting the firewall. It is not obvious to casual inspection and the client sites are rsyncing data around Australia quite happily. MTU=1500 of course. I have a /29 here and don't need to do that NAT/DMZ thing. I just assign the first of the usable IPs to my server LAN NIC and st the routing table in the modem to route the /29 to 192.168.1.2 and it all works. The NAT rule for the user LAN does : nat on $ext_if from $lan to any - $fwint where $fwint is set to the IP address of the server LAN NIC. and so I don't need the WAN address on the box at all.

Great info Simon, thank you. All the DSL modems I've seen here in the USA are ethernet based on the user side and as misfortune would have it, many providers *require* using their particular modem, so the user side of it is all that matters. i wonder if that's s/require/only support/ eg, others will work, but don't expect to be able to call anyone and get a yes that will work, here's what you need it to configure it as blahblah, but that doesn't preclude the modem from being able to function on the network just fine. i haven't shopped around, but i imagine that a DSL modem on the market for end-users to buy would probably not be very successful unless it supported the standard suite/combination of parameters that the DSLAM you're below is going to expect. modems i have PPPoA experience with (second-hand, as the portion of the network i'm on is not PPPoA): speedstream 5930, 5861, 5667, 5200, dlink 504, 3com 812. the 5667 was a trooper, but had limited ability to do inbound forwarding (eg, rdr in pf). the 5200s had a better firmware but weren't as reliable in poor line condition situations (just fine if line isn't marginal) and had no activity LED, and used DSL to indicate both sync with dslam (solid green), training/losing sync (slow blink), no sync (off) and activity (fast blink). kinda ambiguous. the 5861 is cute because it has a CLI and 4 ports, but the services it provides are probably of no value to someone running any unix/linux. the 5930 has IPsec crapola, but again, what value is that to someone who has isakmpd? (outside of being able to avoid NAT-T... woo) i'm willing to be wrong, but i would imagine that if you find a thingy that says it is an A) DSL Modem who B) supports PPPoA, and you get DSL from the ISP and they use PPPoA, it'll only be a matter of getting the right configuration. the hardest thing would be to know the PVC that you should program into the modem so that it matches the cross connect on your port on the DSLAM you're on. tech support *should* be able to answer that, i hope. eg: hi, i'm going through the setup of my DSL modem, and i've got it all sorted out, except i forgot what VPI/VCI to put in here there's at least some chance they won't ask you what modem you're using, etc; at that point you have a potential to be a 30 second call for them. that's pure gold. the thread has kinda gone this way already, but i believe the only way you can get true i don't have NAT on PPPoA, outside of getting a business class service plan (or anything else with static IP WAN and LAN allocations) is going to have to end up with you running PPP daemon/process on your machine. for it to leave your PC to the modem as ATM would be a rare hardware combination. outside of a niche market, it would probably be rare to find one that didn't take a phone cord coming in and an ethernet cord going out. it's possible i suppose there could be a It's all been consumer grade kit, even though a lot of it is in business use, none the less, I have not seen a DSL modem with ATM on the user side (probably because it would be pointless to make it that way).

MODEM mode with this unit seems to be a half bridge mode which actually works. I don't know if the use of PPPoA is common in Australia, but every ADSL MODEM/Router I have seen over here has had PPPoA as an option.

Re: BSD PPPoA Hardware
Another solution is to buy an ethernet modem that supports 'Half Bridge Mode'. I have two such units, an ADSL Nation X-Modem and a Zoom X4. When operating in half bridge the modem does all the PPPoA negotiation with the DSL provider to login and obtain and IP address. Once done it acts as a DHCP server and leases out the IP address just obtained to the connected host. -Private LAN(1st Eth Card)[OBSD FIREWALL](2nd Eth Card)--[ADSL Modem]---PPPoA connection- Internet Once the link is setup the modem becomes 'transparent' and the OBSD see's all traffic from the NET, no reverse NAT, port forwarding or anything and to make life even better the OBSD only needs an Ethernet card with DHCP enabled! I've got a little Nokia IP120 running 3.6 and a EPIAM9000 running 3.7 both running in this manner. The Nokia does IPsec with a Checkpoint box and the EPIA Runs OpenVPN, sweet!

Simon Hi Simon, You seem to be confused on your terms. The term PPPoA means Point-to-Point Protocol over ATM (Asyncronous Transfer Mode). I seriously doubt you're running ADSL over ATM. ;-) What you're looking for is actually PPPoE (Point-to-Point Protocol over Ethernet) since your (A)DSL modem has an ethernet connection to your network and requires PPP to connect to your providers' network. The answer is yes, OpenBSD does a very good job with PPPoE. There are both userland and kernel implementations that can be used. I'm not sure which flavor of hardware you prefer but basically you need a platform that is supported by OpenBSD along with supported ethernet devices. http://www.openbsd.org/plat.html Kind Regards, JCR
