Is it possible to access a NAS server outside of my Wi-Fi?

Question

Bare in mind I know just above **** all about network at the time of posting this. I want to buy a NAS server ith 8TB of space so I can have just a 512GB SSD in my machine with everything on there that I need and everything that really takes up space like films, music and TV shows on the server so that I not only can access them from any device on my Wi-Fi I can be watching a film while someone else is listening to music and someone else is waching a TV show.

Answer 1

If (like alot of home networks) your wifi IP range is on the same network as your wired computers, then you don't need to worry about anything like port forwarding or routing etc.



For instance, your home router LAN IP address is 192.168.0.1 /24 and your wired PC has a static IP of 192.168.0.2 /24.



an IP address is a 32 bit binary number. We split this number into 4 groups of 8. Each group is then turned back into decimal and is a number between 0 and 255.



This is how we get 192 from the first 8 binary digits, 168 from the next 8 binary digits, 0 from the next 8 and 1 from the next 8, giving an IP address of 192.168.0.1



The /24 I wrote is the same as saying a subnet mask of 255.255.255.0 and it means the first 24 digits of the IP address is the network address, and the last 8 bits are for the individual IP addresses of the devices on that network. In our example, the network spans 192.168.0.0 to 192.168.0.255



If we add 1 to the 192.168.0.255 number we get 192.168.1.0 but this address is not on the same network.



So, if your wifi devices are on dynamic IP addresses and get given 192.168.0.100 and 192.168.0.101 etc, I'd put your NAS on 192.168.0.254 (you can't use .255 for a device) so that is it already part of your network.

You can set up remote access to a NAS.



However there are a few caveats,



Generally speaking, a NAS works reasonably well for streaming and file sharing in a home network environment. Problems occur when the network connections are too slow or the NAS processor can not keep up with the demand for large file transfers.



The ideal way to have a NAS connected to data intensive devices is via Gigabit Ethernet.



Although WiFi is convenient for mobility, wireless interference can cause it's connection speed and quality to vary wildly.



Wireless signals are affected by many factors including wall density, electrical interference, directional antenna range, etc. As wireless connection quality varies the connection speeds are renegotiated. The connection may start at 150 Mbps and end up at less than 10 Mbps or drop entirely.



For either Ethernet or WiFi, the connection speed will always negotiate to the speed of the slowest device.



For example, a super fast 300 Mbps wireless n router can only connect to a wireless g laptop at a maximum of 54 Mbps.



In order to achieve Gigabit LAN speeds, all devices in the connection need to be Gigabit. This would include the LAN ports on the router, the network interface cards in both devices and the cables connecting them.



That being said,



If you want to access your NAS via the Internet, you will need to set up remote access via port forwarding on your router.



The main problem here is, all data that you want to access needs to be uploaded via your ISP connection. Upload speeds are usually lower than download speeds. Most broadband Internet services including cable, DSL and fiber are asymmetric. which just means that more of the bandwidth is dedicated to the download channel than the upload channel. For instance 6 Mbps download and 1 Mbps upload. This is due to the fact that most users download much more than they upload.



Another factor is your WAN IP address.



In order to access your device remotely you will need the WAN IP address that your ISP has assigned to your connection. You can see your current public WAN IP address here: http://www.mywanip.com/



Most ISPs use periodically changing (dynamic DHCP) WAN IPs. So you will need to get a static one or use a DDNS service. http://dyn.com/dns/



This will allow you to always be able to access your device via the Internet even when your public WAN IP changes.



I personally use three different brands of dedicated NAS devices, two are configured in a raid one configuration for redundancy, you can even have the device email you when a drive is failing, and swap in a replacement without losing a bit of data.



If you're in the market for a NAS, I would highly recommend the Synology line. I use the DS212j http://www.synology.com/products/product.php?product_name=DS212j&lang=us By far the best user interface and features. It runs Linux and is highly configurable. It includes a download server, media server, individual user security, and too many other features to list. The Synology DS212j is now under $200 at Amazon. http://www.amazon.com/gp/product/B005YW7OLM/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B005YW7OLM&linkCode=as2&tag=excharge-20



Good Luck...

I'm making good profit with a binary option signal software called "autobinary signal". It's great!! Check here for more information ( http://forexsignal.kyma.info )

Answer 4

Yes, you can set up your lan such that your nas is accessible on the wan. You could consider using port forwarding to achieve this.

i have attended a lot of seminars, read counless books on forex trading and it all cost me thousands of dollars. the worst thing was i blew up my first account. after that i opened another account and the same thing happened again. i started to wonder why i couldn,t make any money in forex trading. at first i thought i knew everything about trading. finally i found that the main problem i have was i did not have the right mental in trading. as we know that psychology has great impact on our trading result. apart from psychology issue, there is another problem that we have to address. they are money management, market analysis, and entry/exit rules. to me money management is important in trading. i opened another account and start to trade profitably after i learnt from my past mistake. i don't trade emotionally anymore.

if you are serious about trading you need to address your weakness and try to fix it. no forex guru can make you Professional trader unless you want to learn from your mistake.
