Hi Great Article. You Guyz rock Man!! BTW, I’ve a quick question. If I port forward port 80 to my internal IP then how can i access my router/firewall page again? Because as we all kow the router runs on port 80 and when we enter router’s IP address, by default it connects to port 80 of the router. But now if we port forward this port to the Internal IP then how can we get back to our router? Excuse me if its a silly question

[WM: Most routers let you adjust the access port for remote access to the router. Just set it to 8080 or something other than 80, and you’ll be all set.]

Could you please tell me how to set up a static IP address on this Asterisk box I just set-up. Not a real strong unix guy here.

Great article.

Zoneedit is another great site that allows you to setup your own domain name. It provides DNS service and MX records for your email as well. You can establish 5 zones for free. Additional services are charged at a very modest rate.

Thanks for all the great information on Asterisk.

If my network is NAT’ed, how can I access my server that’s behind the router? In other words, how do I access individual machines in my home network if they all have the same IP address?
– Great website, by the way. When are you going to write the "Asterisk Hacks" book for O’Reilly?

[WM: No book plans, thanks. As for access to individual machines behind the same firewall, the answer is to use different ports. For example, you could have a web server on one PC on port 80, and the next one on 81. If you want to access the same service on two different machines and the service only supports one port, then you’re SOL on one of the two machines. Apache can handle different port addresses. Some other apps can’t.]

http://www.no-ip.com/ allows you to purchase a domain name and apply it to a dynamically changing ip address!

Anything further on changing from port 80 to another port. I can only access my MacMini home page from my internal network. Any access attempts from outside times out. I called my ISP but couldn’t find anyone that has the faintest idea of what I’m talking about.

[Sure. As you’ve learned, another great feature of many ISP’s is that they not only play dumb, they really are. There’s no doubt from what you’ve said that they are blocking port 80. Many ISP’s just don’t like to acknowledge it. Here’s what you need to do. Read our article (above) on Going Live. There are only a couple of steps involved. First, you need to tell your Apache web server to "broadcast" your web site on port 81 in addition to port 80. Open a Terminal window and switch to root access: sudo su. Edit the Apache config file located in /etc/httpd: pico httpd.conf. Search for Listen 80: CTRL-W,listen 80,enter. Add a line below it (with no pound sign) that reads: Listen 81. Save your changes: CTRL-X,Y,enter. Restart Apache. Test it by using a web browser on your Mac web server to go to: http://localhost:81. If your site pops up, it’s working. Then you need to use a domain registrar for your domain that supports proxy DNS records. Omnis.com is a good one. The service is free. Transfer your domain there if you have to. They’re also the cheapest around for domain renewals. Make certain you configure Omnis.com name servers as your default domain servers. Then choose Manage DNS, Enable This Feature for your domain. Click the Help (?) button and read up on Proxy records. You’ll want to delete the two existing A records (# and www). Then create two new Proxy records (# and www) that point to the IP address of your home server on port 81. The syntax is http://youripaddress:81. If you don’t know your IP address, go to http://mundy.org/ip.php, and it will tell you. Wait a day or two, and things should be working swimmingly. Good luck!]
