i was configure Apache on RHEL 4 it works fine on my local network (eth0) but i want to access the site from out side (wan) internet is working on linux machine (eth0) direct from ADSL router and port forwarding is also done. I m trying to access the site through fix ip but i m not getting any thing.

Not enough details to give you any meaningful help. If the web server is up and running on your Linux box, that's it. The rest is either a network configuration issue through your router/switch, or you've got the port(s) blocked via IPtables. Check your firewall and network config.

Since you're using RHEL4, have you contacted them for support? You're paying for it with your RHEL subscription....

Thanks ... I configure this to increase my knowledge i change the apache port 80 to 8080 from httpd.conf and /etc/services file and restart the services, iptables is stop from router port is also changed but again i am not getting web page from out side is there any optional seating in the apache to access out side ?
My aim is access apache web page from out-side if you have solution for this please let me know and if you want any detail from me regarding please let me know.

Again, there's still no details. Yes, we understand you got Apache up and running. But again...this is a network issue. If you stopped iptables, that's fine. But you've still not said if you're plugged in to a router, and if so, if you've done the NAT'ing on that router to allow incoming access to your box.

If you've got a static IP on your DSL connection, then you need to configure your router to allow port 80 into your machine, and NAT it. Since you don't provide details about your router, read the manual and documentation on it. And AGAIN, if you're using RHEL, contact RedHat for support. If you're not paying for RedHat Enterprise, you shouldn't be using it.

Thanks for replay...
I resolved the issue and now it is working fine. Actually the issue with our ISP they don't allow port to access ports 80, 8080, 8000 and 3128. So i change the port on the router and forward to web Server.
