Possible solution for those who see network but can't access inter

[Guest]

I was having the same problem that many were having where I could view my
networked computers but couldn't view websites through the internet, although
I was able to ping them.

I found the solution here: http://blogs.zdnet.com/Bott/?p=10

I was able to disable SPI on my D-Link 4100 and then was able to view
websites through my browser after that. Hope that helps some of you out there.

I'd seen that before, but thanks anyway! However, having to disable a major
security feature in our firewalls is not really a solution as such. But yes,
it might get some people working just to test stuff.

Also, I would try it, if my router allowed me to disable SPI! I'll just wait
for a proper fix...
