please can any body help me ?
i have a cisco router 827 , i have already configure my router to DSL access with PPPoE, but some web site are not accessible from any host on my network, for example www.google.com is accessible, but www.yahoo.com and www.cisco.com are not accessible , i don't know why . there is not a firewall in my router.
when i replace my cisco router by speedtouch router adsl , there is no problem , but i want to use my cisco router for this DSL access. thank for help
