aryoba posted : As you may know, your DSL service is probably not the standard DSL. It could be some Ethernet extension over POTS (Long-Reach Ethernet) using something like Cisco 500 series LRE modem on your end as the CPE; or it could be something else.

Whatever technology the ISP uses in place, make sure you talk with somebody technical that knows what s/he is talking about. Without the correct info from the ISP, you will have a hard way to configure your end.

Just on a quick side note his location sounds... international... While the FAQ and standard configurations are great, the one thing i have learned over the years is that you should never ever trust international telecoms to act like northamerican telecoms (particularly APAC ones)...

I have seen them sell "ADSL" service that was really ethernet all the way (no ATM or ADSL ITU and ANSI-ish protocols to be found lol) just straight pppoe or DHCP on an ethernet line (the "modem" was a puppet from some shanghai company that ran a perverse propritary protocol)
Most companies with solutions like that will just tell the customers that they have to use the CPE device provided as their nat router because the providers setup is so nonstandard. How much fun it can be to troubleshoot issues with small non-US providers that have equipment from companies with unpronouncable names.

And yep my spelling is awful at 5:30am. Oh what a hangover, I shouldnt have drank the koolaid at the nexus training yesterday.

That is what i think we have right now i seen your FAQ and wondering what the heck is our dsl service here. i talked to them yesterday if its possible to give me the information such as vti or the username and password and they are not sure :-(
i will draw our diagram today you we can all see the setup. is this a first time to you guys to encounter this kind of internet setup?? anyways i am thankful for all the effort you've given and will give to me.

thank you

TomS_ posted : Have you been on the juice deepblackmag? ;-)

Yes, if you run PPPoE over an ADSL connection it is PPPoEoA ("PPPoE over ATM"), but that wasnt the point. The point was that F430 claimed that I was wrong when I said that ADSL doesnt run over PPPoA. PPP is an encapsulating protocol which is transported via a layer 2 protocol over a physical medium.

The protocols which make up ADSL itself sit in between the physical media (layer 1) and ATM (layer 2). Those protocols are what allow the modem and DSLAM to sync, negotiate transmisson speeds, handle and attempt to correct errors and so forth. They would probably be considered part of layer 1, since this is where the transmission of bits happens, and bits cant be transmitted without both ends agreeing on how that will occur.

nosx posted : Did you have LEGO blocks to play with when you were growing up? The protocols used to provide broadband service like "ADSL" can be SNAPped together (lol ATM pun!) just like legos in a bunch of different ways. Each combination of those protocols can work and provide "adsl" service if the right equipment is sent to the customer (the right horrible little speedstream ADSL modem for example). To use cisco equipment you need to understand how your local service provider is configured, if they are really just PPPOE(oa?) or some bridged PPPOA solution, or something else entirely possible branded under the umbrella of service they are calling DSL these days. Wikipedia is a tolerable source of information for beginners but tends to have its little inaccuracies from time to time, you might start by reading through some of their descriptions and then hit ciscos all encompasing list of ways in which to never configure your ADSL interfaces.

You got that wrong. Just ask any Qwest user. Qwest is beginning to switch to PPPoE but still use mostly PPPoA.

I'm sorry, but you appear to be mistaken.

ADSL does NOT operate over PPP of any kind. ADSL does, as TomS_ pointed out, operate over ATM.

PPP is simply a form of encapsulation that runs on top of the ADSL circuit. PPPoE or PPPoA is not required to run ADSL at all.

Please don't correct people unless you know what you are talking about.

Umm, ok...

Just what are you talking about?

I think you have turned ADSL on its head and have everything mixed up...

its adsl over ppoa, the problem i encounter is the isp doesnt want me to replace their adsl modem

ADSL doesnt operate over PPPoA. PPPoA is "PPP over ATM", and ADSL uses ATM to transport data from end to end.

Do you know what mode your ADSL service operates in? Do you know if it is "bridged" mode (RFC 1483", or do you need a username and password to login to your ISP (PPPoA or PPPoE)? You should be able to confirm this by looking at the configuration of your current modem/router.

The ISP probably doesnt want you to replace their modem because their staff are familiar with it, and if you need help they will be able to help, whereas once you replace it with the Cisco they may no longer provide support for you while the Cisco is on the line. But thats no big deal, if you have issues with your line you simply swap out the Cisco for the original modem and they are none the wiser.

Once we know what mode your current modem/router is in its much easier to point you in the right direction for configuration of your Cisco.

arieljavier posted : Hello everyone, I'm seeking for technical assistance any kind of help is highly appreciated. thank you in advanced.
here is our situation:
we have dsl internet with 5 public ip address, i allocated one for our web and email server and one for sharing the internet using the untangle network gateway.

honestly i'm now trying to learn the cisco equipment :( and i requested to purchase a cisco 1801 router to replace the untangle network gateway luckily they granted my request.

here is the problem, i am familiar with linksys, dlink and other soho router its my first time to use a cisco and i cannot find a way to use it with our existing internet connection.

this cisco have the following port 1 adslopots, 1 isdn s/t, 8 port switch and fe0 .

i tried to use the sdm bundled in this router but i cannot figure it out.

i call our internet provider and asked them i can i used the router adsl o pots for the internet they say no :(

initially i just want to use one of the public ip i have in this cisco1801 router to share the internet.

i know i sound dumb but please any technical assistance is appreciated.

thank you again
