NOTES:
Since the beginning of October, we've had nearly two million downloads of Lab Rats.
We're beginning to get the feeling that you like our show.
Why the ominous music, then?
Well, you like us too much.
The bandwidth costs for Lab Rats are starting to kill us.
You can help keep us going by donating via PayPal.
There's a link from the Lab Rats home page.
Even $2 would help out.
Don't make Andy sell his cats to pay for bandwidth.
That just wouldn't be right.
More techie stuff...like eating the props.
DMZ: Demilitarized Zone
- While DMZ stands for demilitarized zone and takes its name from warfare, there is no actual gunfire involved.
- The DMZ is a "zone" on your network that is directly accessible to cmputers outside your own network.
- Items that are DMZ'd could be a stand-alone computer, or an IP-enabled device like a printer or a webcam.
- The key is that even when you grant access to a device on your DMZ, the rest of your network is protected.
- Businesses may use DMZ for email, web servers, FTP, and other services that need to be accessible to the public.
- On a corporate DMZ, however, devices are often located between two firewalls, where as personal DMZ uses only one.
- NAT, or Network Address Translation, assigns your internal network IP addresses that do not exist on the outside network.
- When data arrives fro a computer inside your network, NAT redirects that data to the proper computer inside your network.
- Computer's on the outside of your NAT cannot see the internal IP addresses.
- It won't redirect unrequested data, only data that has been requested from the inside of your network.
Setup DMZ:
- Access router configuation
- Click advanced button
- Select DMZ
- Click enable
- Set the IP address of the device
- Click apply
- By putting a computer onto the DMZ, you are removing the protection that the router's firewall provides.
- Any device you place on the DMZ should therefore never contain sensitive data or backdoors to your network.
To obtain IP address:
- Click start
- Click run
- Type cmd, then enter
- Type ipconfig, then enter
- Listed with be your IP address
- Type exit, then enter
- If you want to make sure that the device you choose to be in the DMZ is always there, some manual config is in order.
- You'll want to set its IP manually instead of using DHCP to obtain an IP address automatically.
- That way you'll have the same IP address every time the device restarts, without manual intervention.
To Set Static IP Address:
- Click start
- Click control panel
- Click network connections
- Right click on current connection, then choose properties
- Find & click Internet Protocal [TCP/IP], then choose properties
- Click on Use the following IP address
- Type in the assigned DMZ IP address
- Your Default address: 192.168.0.1
- The item you set up on your DMZ will be accessible through the same IP address as your WAN address on the router.
- To access DMZ device in a web broswer type: http://WAN IP ADDRESS
