httpd problem or something else

Hi,

I have a bit problem with my server.. The httpd server seems to be running and all but the websites which are hosted on it are not opening .. any hints what else it might be, here is what I get when

/etc/init.d/httpd status

Thank you for your replies

What error(s) do you get ? Did you check error log ?

here it is last 30 lines :

tnx

Is port 80 open ? What does the browser say when you connect ?

Yes it is open. Here is output from firefox "Failed to Connect
Firefox can't establish a connection to the server"

Thanx

Do you have a firewall in between ?

Sure I do .. but the thing is .. everything was working perfectly for like 2 months or so .. and now it just stopped .. thats a problem..
