Hello,
I'm trying to use a cisco 887 router for a domestic PPPoE DSL (italian ALICE DSL).
I can ping public host but I can't surf. Only a few web site can be reached and very slowly, i checked dns and name resolution is ok.
No problem with my domestic router.
Can you please tell me a right PPPoE configuration for my router?
I tried several MTU and MSS value but without success.
(do I have to set mtu or ip mtu?).
Is there anybody can help me?
Thank you very much

Hi Paolo,
Thank you very much.
I can see a little number of web site, and most of allonly in the first page.
The router still doesn't work, while my domestic router works perfectly.
The value I used are the ones you suggested in the answer to my post but they don't work.
I also tried to chagnge IOS firmware without any success.
can you help me?
Thanks

And remove any other default route you may have.

Thank you paolo,
in a couple of hours I'll try the new configuration.
as regards IP INSPECT FW IN i tried yesterday to disable any firewall but without any success (that configuration line is a result of the last tests).
I didn't try to remove default routes using ipcp default route and to disable ip virtual-reassembly.
Let's see tonight if it will be ok (I'm testing the configuration in my home adsl connection).
I thank you very much

It doesn't work.
I open only a few web sites, very slowly.
Ping and name resolution works correctly.
If I use the router to connect as a ezvpn client to a central site with split tunnel, I have no problem to open web internal pages (printer gui, intranet web site and so on), i can ping and dns outside but i have the same issues with web external sites.
I noticed that DSL interface ATM0 shows capacity used 100%

Please post the complete configuration, only remove any public IP and password.

Hi
How can Cisco releases the CCNA Discovery and Exploration documentation with full of corrections in it. If you need proof you check my blog www.CiscoMistakes.blogspot.com. Take some necessary action. I am able to find 1 correction in 15-20 pages. Some of those are published in my blog. If you are not concerned with the documentation please report this to the concerned team or person.
This is Satya Rao (Mr. Perfectionist), a 28 year old South Indian guy, I have been taking CCNA training from the April 19th 2010, in one of the Cisco Networking Academy named IGIAT (Indo-German Institute of Advanced Technology) in Visakhapatnam, South India.
We know how important a proper documentation for any software or hardware. It should be given one of the major importance, without proper documentation the software or hardware is useless.
While I am reading your CCNA Discovery and Exploration materials I have found some corrections in the documentation. More than 300 corrections in the module 1 and 2 of CCNA Discovery and Exploration.
My correction checking includes spelling mistakes, punctuations errors, formatting errors, technical mistakes, diagrammatic error, etc.
I don’t want anyone to point out my favorite company’s documentation. Yes ordinary people may not find all of them but they will some of them.
Microsoft Windows is a 100% correction less documentation. I have studied lots of their documentation and unable to find not even a single correction, why not Cisco develops that kind of correction free, documentation to the world. Yes, it’s possible with me, the Mr. Perfectionist.
Please give me a chance to make it 100% correction less, yes the documentation is 99.999% good. But not 100%. Why should we take chance when Mr. Perfectionist is available?
Of course small punctuation corrections are not so big in terms of technical issues, but the high quality documentation must need everything to be high.
We all know that how many times it was checked before finalizing the documentation but still I found these many corrections.
If you want to test my talent or capacity give me your latest finalized version of any technical documentation and let me found the corrections in that documentation. You came to know how fast I will give you the 100% correction less out put.
Just imagine I have found these many corrections after you people done all kinds of proofreading before releasing to the world, how much useful I will be if I am in your documentation department.
I think you know, how hard it is find mistakes from a very great companies documentation like Cisco, (if not hard you would have released it 100% correction free to the world) not 5 or 10, I have found hundreds (still finding). If you really understand my talent you must give me a quality analyst job in documentation.
I know there are no vacancies but a person like me you should place me, to get better output, as the quality analysts there, unable to give the 100% quality.
I am ready to sign any kind of bond you wish.
You can fire me out at any time if you not satisfied with my work.
One of my weak point is I can’t tolerate if something is wrong or someone doing wrong. With this weak point I can easily find out mistakes in any documentation with ease at the maximum speed possible, which a computer can’t do.
Please someone recognize my work and effort and help me by providing a job with minimum possible pay. Willing to work 12 hrs a day at any time of the day.
I was worked as a proof reader in a medical transcription company for John F Kennedy hospital of California for one year.
I can give you results more than you expect from me.
Most importantly I need a job in my favorite company, Cisco. Willing to work from home too.
I think its not a big problem for a big company to give a job to a boy whose father died at his age 5.
Please give me one opportunity to prove myself.
If you came to know about this blog through an email, please forward the mail to the concerned person in the concerned department would be appreciated. (If not, humans help the humans who, will help the human kind.)
Thank you very much.

I have created one blog with some of those correction please check it.

I have not created this blog to generate some revenue, some popularity, or to point out the Cisco's mistakes to downgrade its standards. I just want to be one in the Cisco organization technical documentation team, for correction free documentation.
