Unhappy Apache/DHCP/Cox Cable


Apache version 2.0
US Robotics 8000a broadband router

I have correctly configured apache yet i still can't get it to run properly...I'm not sure if this is due to my ISP or faulty router configuration options. I searched google and couldn't find a solution to my problem. The problem is that my domain will not work outside of my network!

I can connect to 127.0.0.1 and 192.168.123.184 and get the default apache page, but when I try to connect to my external i.p. address or my fully qualified domain name, my web browser just hangs. I've had friends try to connect without any luck. I originally was running apache with my router allowing port 80.

I've had friends port scan me and it showed port 80 as closed. Because of this I tried running it as a virtual DMZ host. After doing this a port scan revealed port 80 to be filtered. At this point there was still no luck connecting to my domain (extremelinux.us) I was told that there shouldn't be any problems at all if I run my linux box as a virtual DMZ host on my router.....my apache httpd.conf is in workin order...in fact, there are no problems with apache. Ohtherwise it wouldn't start up.

I was hoping someone with prior experience with a similar problem could enlighten me as to what THEY did to fix it. Could it be my isp? I'm completely baffled...any advice would be greatly appreciated

Try changing to see if it will allow access via externally via another port, instead of 80. Could be very well that Cox is blocking port 80.

Yes, I believe you are correct...I think Cox cable does block port 80. I came across a lug email that gave me a hint. Here it is:

I don't know if I can redirect the connection to some other port due to my router not having an option to do this...but if anyone else is having this problem I hope this helps!

Well I called my ISP and found out what the problem is....Cox Cable blocks incoming connections on port 80. I can't even count the number of expletives I've said since I their tech support and found this out. So to make a long story short, I'm switching ISP's.

All's well that ends well!!

if you are running behind linksys router, your needs to be in the DMZ zone ( by ip selection) or open any ports through the router, and if cox is blocking port 80 for web
you need to assign the httpd to listen on a different port.
Then there is the dynamic dns you will need if you are running dhcp for your server to get an ip address (even if it is static behind the router.... take a class at community college.... i dont have all the answers...
i got mine running, but the cable company states in your contract, in general they dont want people running web servers because they cause to many problems due to bandwidth and misconfiguration.

DSL providers are generally much more accepting of running servers on their networks, but make sure you read the contract. Nearly all the cable providers block server ports like 21, 25, and 80. Some even go so far as to block you sending to port 25 OUTBOUND.

My DSL provider is speakeasy.net and they not only allow servers, they advertise that they're "server friendly".
