lost (*some*) internet connections after yum update
 

Hello all,
My FC machine has developed an issue after its most recent yum update (everything was working fine before then).
I updated my machine, and now the internet connection does not work with Firefox or Konqueror, although I can access my router from both.
My FrontPage extensions no longer work (when trying to login from another computer) but my FTP does.
Again, I can't access the internet from the FC server machine, but the family website still works (see link below).
My original thought was that it was an iptables issues, but things look ok in that file. My next thought was some sort of SELinux issue, but the SELinux is disabled. Is there another config file that would control what I'm having problems with?
Thanks for your help.

This is one of the sites that is hosted on the computer.

Again, the site seems to work fine (meaning that internet traffic is working), but I cannot connect to internet with with Firefox or Konqueror.

when you cannot access the internet what's the error messages from browser.
how about the setting of tcp wrappers(/etc/hosts.deny|hosts.allow) and audit(/etc/audit).

you'd better to have a strace testing:
strace telnet www.yahoo.com 80
to make sure whether it's the browser fault or the system's.

I was able to track down and fix the problem. It was a DNS issue.
