Internet does not load pages completely or not at all
I have searched the forums and have tried a few different things with no success. What I am running into is that on my Mandriva 2007, and Fedora Core 6 distributions my internet seems slow or will not load certain pages. For example on Linuxforums.org it will load just fine except for "linuxforums.us.intellitxt.com" I tried loading this site by itself but it only errored out. On my Mac it however loaded and redirected me to another site. What it seems to me is that it is either the ipv6 which I have disabled or the DNS servers. I tried mannually configuring the DNS servers, but for some reason it seemed that it would not load anything afterwards. I am going through a LAN to a VPN firewall then to a modem. We have a T1 connection here so it is plenty fast.
My machine is a Pentium 4, 3.0 ghz, 1 gb RAM
Currently my machine is getting the DNS servers from my router via DHCP the DNS servers are 18.104.22.168 and 22.214.171.124 Thanks for the help in advance. This problem may have been solved in other forums and if you know of any I would be happy to know about them also.
