Which SBC Company do you get Your Internet service from and which router are you using?

Ok...This is a General Query on IP Addresses...The Router is the Netopia Cayman 3546

see »Cayman Routers »[SBC] How do I configure a Cayman to work with Static IPs? (Bridged) for info on how to setup your statics.

Callin in from IND..This is a general query on IP Addressing and i'm troubleshooting an issue for a Customer

reply to davidg
Thanks for replying..what i need to know is what these IP Addresses are and how they are used ..I know that the Router Address is the SBC's Gateway IP but i'm confused on the Primary DSL IP and LAN IPs...How are they used ? Was told that i've 5 usable IPs ...one Primary IP and 4 LAN IPs...also what is the WAN IP ?

it is simple to setup the cayman.

follow the FAQ and you will have it setup in no time.

the basics of it are as follows:

configure--WAN
set the ATM to RFC-1483 bridged.
turn NAT OFF
set WAN ip to 66.105.x.x
subnet 255.255.255.252
gateway ip = ???? they should have listed this. if not, leave it at 0.0.0

configure--LAN
LAN ip 66.123.x.x
subnet 255.255.255.248
DHCP server range 66.123.x.x
subnet 255.255.255.248

you must click the yellow triangle at the upper right, and chose save and resatart IF it says validation passed.

this will allow for the ips to be assigned to each machine directly. sorry, but the user cannot use NAT when running a routed subnet such as this. you are limited to 5 devices behind the cayman. the only way around this is to put another router or 2 behind the cayman and hook the pcs to those routers, but this complexes the issue and requires the user have a little better than a basic understanding of networking to get it setup. plus, i guarantee you that the user will lose some hair in that instance!

this setup is called a routed subnet. the WAN ip is the DSL side of the cayman, the LAN ips are the ethernet or local side of the cayman. the primary ip is assign to the caymans LAN interface, the LAN ips are assigned to devices on the customer network.

The following applies if you have Atech/SBC, other SBC areas may be the same but I am NOT sure about that fact.

You actually have 8 addresses: Two are for SBC Wan network routing, 1 is the Router's and 5 are for your use, You log in PPPoE using username@static.sbcglobal.com or username@static_ameritech.com, you will ALWAYS pull your Router IP# which is the second to last in the range of 8, then following your router's setup you have the 5 for your LAN.

If you want detailed help go over to the ATech/SBC forum

Thanks very much for the reply.i'm n't too techy so could u tell me what is a WAN IP and how is it used ? I know i've 4 usable LAN IPs but they are i suppose Public LAN IPs.They are not Private IPs....so does that mean that anyone on the internet can connect to the comps that are assigned those LAN IPs.Could u also tell me which IPs are the 5 usable IPs and which are the IPs for the SBC WAN Networking ?
I had listed the IPs that was received by the customer in an earlier post on the forum...

did you not READ my post a couple replies up? i gave you that info.

routed subnet account are not PPOE.

Depends of which SBC company they have >> I have no idea what IND means(Indiana? Indianapolis? India? well maybe not India) if it is Ameritech/SBC unless things have changed they stil run PPPoE on Statics.

Please do not touch that customer's router. If you have to ask what a WAN ip is then you should not be in there.

WAN= Internet
LAN= Local Network

If they have a WAN and a LAN then just tell them the wan ips go to the wan interface. Please do not attempt to configure this. Just transfer to tier 2.

Your the reason I hate calling tech support for anything, you know nothing of what your doing, and just reading information from your computer screen.

I've talked to more 'techs' that have no clue what they are doing, other than what the screen tells them to do, and all of the smart techs are the ones actually given permission to send out contractors to fix something(Tier 3 usually), which obviously you are not.

I know that I will never use SBC if that is the kind of customer service I can count on if there is a problem. Tech support like yourself is why I don't like using broadband in general, in the cases where I must call tech support, I cringe when I get people who know less than the average high school student, reading from their screen trying to sound like they know what they are doing.

Too funny..

reply to binesh_28
Did this guy really publish a customers static ips? Yes the mods removed them, but isn't customer information supposed to be private?

Yep, this employee violated company policy by publishing customers private information, even if it was their ip address. This, and other reasons is why companies don't like their employees going public.

People like this person show they they have no working knowledge of the field they are working in, and make the company look bad. Not to mention breaking privacy rules in this case.
