Can going through a router block internet sites?

[biffenbob]

I have 3 computers going through a router to a modem, and my question is can the router block my computers from going to sertain sites? I ask this because for some odd reason all of my computers on this network cannot get to a couple of diffrent websites, such as google and hotmail. If it is the router (which I doubt) how can i fix this? If it isnt, any ideas what it might be?

If your router has a built in firewall then you could try disabling it. Also, make sure you have the latest firmware for your router. Check you haven't got some kind of virus/spyware that prevents you from accessing certain websites (though i dont think it's likely). Finally, check your browser compatibility.

IN the UK, this can be caused by an MTU setting that's too high for those using AOL, and possibly others. I don't know if this would be the case for you, but maybe worth checking with your ISP's tech support.

Most likely a firmware update for the router would solve the problem.
