What is Port Forwarding


Port forwarding is the literal act of forwarding a network port from one single network to another. This networking technique is used to allow external users to reach ports on private IP addresses from the outside via a router. An example of port forwarding would be to allow remote computers, such as public machines on the internet, to connect to a specific computer inside a private LAN. In typical home networking setups, internet access is through a DSL or Cable modem and these modems are commonly connected to a router. The router is then connected to several networked computers by WiFi or Ethernet. When communicating online, the router is the only device that can be seen on the internet as it holds a public IP address, but all computers behind the router will be invisible. Port forwarding is necessary for the router, as it will need to distinguish which direction to send information received from both the internet and the networked computers. For more information on Port Forwarding and Routers, check out PortForward as they are an excellent source of information hundreds of types of different router models. If you are looking for corporate support for router troubles and port forwarding, contact ComputerServiceNow for Cisco Router Help and choosing the right routers and firewalls.

I Spy with My Eye-Fi


It is like out of a James Bond movie, a wireless SD card that sends your pictures to your computer at home! It’s much faster than emailing pictures from your cell phone. All Eye-Fi Cards come with everything needed to set up and connect to your home Wi-Fi network, then insert the card into your digital camera and start capturing memories. It stores pictures like a regular SD card and as soon as you come into your wireless network your camera automatically downloads your pictures onto your computer at home. Eye-Fi Card works with 802.11g, 802.11b and backwards-compatible 802.11n wireless networks Eye-Fi software works with Windows XP, Windows Vista, Mac OS X (10.4 and 10.5) Eye-Fi software works with Internet Explorer 6 and 7 (Windows only), Firefox 2.0 (Windows and OS X) and Safari 3 ( OS X 10.4 -10.5) Eye-Fi card requires an Internet connection for setup and a wireless router with DHCP enabled for wireless transfers Eye-Fi Card works with virtually all digital cameras that accept SD memory cards. Here is a list of compatible >cameras Easy download is not the only feature, it also has crime fighting features! A lady who was vacationing in Florida was devastated when her camera bag was stolen from a restaurant when she accidentally left it behind. When she got home she not only received her vacation pictures but also the pictures of the thieves who actually worked at the restaurant! While the SD cards run about $100.00 a piece, as a photographer myself I can appreciate being able to download my pictures from a shoot location to my computer at home. It could mean not carrying extra SD cards, providing unlimited picture taking. Not to mention that if stolen my camera could eventually find its way back home.
