A problem occur on cisco router with adsl module

I have feazed by a strange phenomenon for a long period. Hope get a help from here.

Through a completed configured 2600 with cisco adsl module ,i can open all websites on Internet except one that are built on an IBM server with solaris OS. Next i replace cisco router by adsl dialer device provided by ISP .then everything is OK.

I have changed the default MTU size of the cisco router's interface to 1492 ,the problem is still existing.So haw can i solve it?

Not any access-lists or other settings restrict this access.

Thanks for the input

Re: A problem occur on cisco router with adsl module

Yes you have problem with PPPoE configurations to adjust the MTU size ,Try adding a command in the ethernet interface " ip adjust-mss 1452"

Please refer this document for the explaination
