howdy, i'm at wits end 'cause nobody can access my apache server, here's the deal:

i recently signed up on dyndns.com and setup a dynamic dns. i put a program on my computer to update my ip from the internet every 10 mins as i am using Verizon DSL. I also set the DMZ on my linksys router to my computer's ip adress. So thinking that i have that part all setup, i setup a simple apache web server. I can view the the page (dasratsel.ath.cx) on all the computers behind my router, but when i ask if anyone else can view it, they all say that their requests just time out. am i missing something?

maybe your ISP block port 80 ?

you can test it out by going to https://grc.com/x/ne.dll?bh0bkyd2 and try probing your port 80

if the result is "stealth", it is blocked either by your firewall or your ISP...

if it's "closed", the webserver isn't configured correctly

if it's "open", then anyone can access it...

-----

if you're sure that your firewall isn't blocking port 80, then you can change your webserver to use another port, like 8080 (which is commonly blocked too) or 8088 or whatever...

then you need to add the port info when you tell people your dynamic hostname, eg: http://mysite.webhop.net:8088

-----

and as far as I know, dsl's IP won't cahnge too often... so if I were you, I won't use the 10 minutes auto updater and I'll use static dns on dyndns.org :)

k -- i found that port 80 is in stealth, so i changed the port in apache to "Listen 7777" to an arbitrary number (7777). now the only way i can get to it is http://localhost:7777 and when i go to my DNS:7777, i get the lovely "this page cannot be displayed" -- is there something that i'm missing in apache or the like?

"and when i go to my DNS:7777"

what do you mean exactly?

you accessed locally by typing http://localhost:7777 <-- that's correct, if it's normal (you can see your webserver), then the next step is:

- probe port 7777 from shieldsUp... same method as above (stealth/closed/open)

- if it's open, then everyone can access, by typing http://your_dyndns_hostname:7777 just like you typed http://localhost:7777 locally

---

you don't need to change anything else on dyndns.org unless you want to follow my advice above (about 10 mins update & static dns)... :).

---

for troubleshooting, ask someone to type:

http://your_ip:7777 first (after shieldsUp said your webserver's port is open, whether it's 7777 or any port you've set)...

if they can see your webserver, it already "opened" to the internet... then you can start playing with dyndns account types :)

if people still can't access your webserver by typing http://your_ip:your_port although shieldsup said that your_port is open, then maybe you're not using a public IP? in that case, I think you cant do anything... :(

yea -- my ports are acting as they should be (closed when my apache is off and open when apache is on) - guess it's some ideosyncracy with verizon or something -- thanks anyway
