Cannot view some internet pages
I am on a windows box that is connected through a linux machine. This problem did not always exist. It definitely did not exist before I upgraded from Slack64 13.1 to 13.37. I kept the same config files, just copying them over. It could also have come from a botched installation of deluge, a linux torrent client? Or maybe it was using opendns.com services? I don't know. I'm just guessing as I have no clue as to what the cause is.
Most webpages are fine. But a few like finance.yahoo.com are messed up. Sometimes credit card and banking sites get messed up as well, but they are not always messed up.
Sometimes I get "connection closed by remote server" in opera or "the connection was reset" in firefox or "Internet Explorer cannot display the webpage" with ie or "This webpage is not available" with google chrome.
Sometimes pages look like this: http://i.imgur.com/SZrBX.jpg
I have tried both dhcpd and dnsmasq with same exact result. The problem does not exist when connecting my windows box directly to the modem and therefor the internet.
