I was issued a static IP from bellsouth for my home DSL service. From what i have read, you do not set up the router with the traditional IP, Subnet Mask and gateway. From what I have read, the router needs to be set up as PPPOE client with the modem in bridge mode.

Can anyone give me some guidance on how to set this up on a 533? I have read in the os manual how to set up a PPPOE client. Just wondering if there is more to it before I attempt this.

I currently have the modem set up as a DHCP server with the 533 being the DHCP client.

Any advice will be greatly appreciated.

Thanks in advance.

You need to put the modem in bridge mode. Right now it is doing the PPPoE'ing and giving out nat'd addresses from itself. The modem should have a webpage on it that you can change settings on it. Contact Bellsouth for more info on that if you can't find it.
Once you bridge the modem it is basically a phone line to Ethernet adapter, if you want to think of it that way. That's when you need to setup the router as a PPPoE client and add your static IP address to the interface.
Then you need to make a src-nat rule with the action of masquerade for your internal network to see the outside world. And you will also have to make a default route most likely that says if the dst is 0.0.0.0/0 then the gateway is the gateway ip that you are given from Bellsouth. You will also have to setup a DHCP server on the box to hand out non-public ip's.

Thanks for your response. You touched on one of my main questions. Does the PPOE Client interface (Ether1) get issued the static IP address from the Modem, or do I set the static ip to Ether1. In other words, does Ether1 act like a DHCP Client, or a static IP.

I think the PPPoE Client will create its own interface, and you assign the static Ip to that interface, not Eth0
Eth1 would be your lan side, as in what you connect computers to, and you need to have a DHCP server on that interface.
I'm going to a friends house in a few hours to setup a router, and he was Bellsouth DSL, So I will post the config for you to look at.

Thanks so much for your help.

I already have the backside of the network up and running correctly. All I need to do here is to get off of the dynamic IP and switch over to the static IP I just got issued.

It seems fairly simple, seems like all I need to do is switch the modem to bridge mode, and then assign a client PPPOE to the ether0 interface where the ethernet between the modem and the router is connected.

Not sure if that is going to mess up any routing or not.

Just a little unclear about whether I have to specify the static IP on the router or whether the bellsouth modem assigns it for me.

Look forward to seeing the configuration when you get back.

Ok, so i forgot to grab the config.
But heres what you do.
Add the PPPoE client, with your login and password and select use peer dns
it will add the static ip for you. and the default route. Its not DHCP its some PPPoE magic, but it worked great.

Thanks for your help, worked like a charm.

I simply disabled the DHCP Client on the router, added the PPOE client, changed the nat rule from ether1 to the PPPOE interface that was created and all is well. Made sure to use the "PEER DNS" and the "ADD DEFAULT ROUTE".

Cool, I'm glad to hear it worked well.

Just one more question if you are still around.

How do you get into the modem interface now that the 192.168.1.254 is no longer being assigned?

I'm Not sure,
Ask bellsouth. I think you should still beable to get to it, if you disable nat and give your self a ip in that range.
Or hook right up to the modem. I'm Really not sure.
If you find out let me know, will help next time i need to know.
i take it you already tryed that ip in the browser, and make sure that your internal range isn't 192.168.1.0/24 or it will over ride that, because the route will say if the dst is 192.168.1.0/24 go out lan0
not wan like it should to get to modem.
I think it still works, you just have let the router push it out the external interface. I'm guessing your internal range is 192.168.1.0/24 and thats why you can see it, change your internal range to 192.168.0.0/24 and try it.

Kind of got lost in that one. My internal network is 192.168.2.0/24.

If I type the 192.168.1.254, it of course gives me a page can not be found because I am on a different subnet.

Tomorrow, I will try assigning my computer with the address of 192.168.1.250 and hook the modem directly into the computer and see if that works.

Other than than, not sure if I could add a route somehow ot get to it.

Great Information NickOlsen & phil1995!

Information still works for the latest updates 5.13 & RB751xxx!!!

Kudos, instructions also worked for us.

Just thought I'd chime in for anyone using AT&T business class with a block of static IPs - the crappy DSL modems AT&T uses require a separate MAC for each IP. I've gotten around this on Mikrotik routers by building half a VRRP pair for each IP and assigning the static IPs to each VRRP interface.

To reach the modem page when in bridge mode, you just need to set a static IP in the same subnet to the eth port that is connected to it.

If your modem was 192.168.1.254 before you put it in bridge mode, just assign IP 192.168.1.10 to your interface, and you should be able to connect to 192.168.1.254 (just check that you don't have any firewall or NAT rules that may interfere with it)

Can someone comment on setting up AT&T (was BellSouth) pppoe with a block of 8 (5 usable) static IPs?

I have a block assigned and I know my pppoe user/password. The modem is in bridge mode. I created a pppoe client on interface ether1. When I activate the pppoe client it connects and receives an IP from AT&T. That IP changes every time I disconnect/reconnect and it is not my static.

I tried to manually assign the first usable IP in my range to the pppoe interface, but now the interface has two IPs and I am unable to ping the static gateway IP.

Any hints on setting up pppoe with AT&T and a block of static IPs?

Thank you,
James

Morning James, I know your post was from a long time ago, did you get a reply about using static IP's with a dynamic PPoE service.
Thank you in advance, David.
