D-Link 6850U - Port Forwarding
« on: October 11, 2016, 01:00:34 AM »
Hi all,

I have read the introductory posts, but still no success.

I'm trying to port forward for 'soulseek' application on a windows 10 based machine. Single router, single PC.
On the router (D Link 6850) I seem to enter the correct input, but when checking if the port forwarding helped the answer is negative.

Maybe I'm getting the IP wrong? Which IP should I enter? I couldn't understand the answer to that from the introductory post.
Where to copy from the IP (windows 10 machine) ?

Here is the data I input to the router:

Name: soulseek
external port start: 63633
external port end:   63634   
protocol: TCP   
internal port start: 63633   
internal port end: 63634   
server IP address: 10.0.0.1   
wan interface:  ppp1.1   

The port names are those mentioned by the application (soulseek)

Any ideas?

#1 As how to check what the IP Address is/are, Subnet Mask is/are, Default Gateway is, MAC Address(es) is/are, DNS Server(s) are of your computer, it depends on the OS and Version.

Note: This example assumes that you are on Windows XP, Windows Vista, Windows 7 or Windows 8, Windows 10.

a) Press the Windows Start key to open the Start screen.

b) Type cmd and press Enter to launch the command prompt.

Note: You do not need to click on anything on the Start screen—typing will automatically initiate a program search.

c) Type ipconfig /all at the command prompt to check the network card settings.

d) If not on Windows XP, Windows Vista, Windows 7 or Windows 8, Windows 10 and you do not know how to check that network info - then post what is your OS and Version is.

#2 The Default Gateway of your computer should be the same as the LAN IP of the router.

#3 If it is not, please post and we will go from there.

#4 Go to http://whatismyipaddress.com/

#5 On that web page is the non bogan IPv4 (Public) Address that users from Internet use to connect to you.

#6 In your router's UI, go to Status -> Device Info

#7 The IPv4 in there, should be the same.

#8 Important note: This is not to say that the non bogan IP Address has to be Static.

a) Example non bogan IP Address is 999.888.777.666 and in the router the WAN IP is 10.0.0.2 - this is not ok.

b) Example yesterday's IP Address was 999.888.777.666 and today's IP Address is 999.888.777.555 - this is ok.

#9 If your router you do not see the non bogan IP Address, it first depends on the WAN IP in the router.


a) If the WAN IP in the router is in the IP Address Range of 100.64.0.0 - 100.127.255.255, then CGNAT/NAT444/LSN is present.

--

If you want more details about CGNAT/NAT444/LSN, you can look at

http://en.wikipedia.org/wiki/Carrier-grade_NAT

The possible fixes to fix your issue if CGNAT/NAT444/LSN is present.

#1 Have them in their NAT router forward the ports to the IP of your router..

#2 Upgrading the type of plan that you are on with your ISP so that you get a non bogan IP Address.

For example if you are a Residential Service Plan, consider going to a Business Service Plan.

#3 Consider switching to another ISP that can give you you a non bogan IP Address.

#4 For the long term future, get IPv6 working.

--

b) If the WAN IP in the router is any of these IP Address Range(s):

From 10.0.0.0 to 10.255.255.255, from 172.16.0.0 to 172.31.255.255 OR from 192.168.0.0 to 192.168.255.255 now it matters the type of NAT router it is.

-> Based upon your type of router, CGNAT/NAT444/LSN is present ( see above for fix ).

d) If the WAN IPv4 was not any of those, it would be a good idea to check to see how the non bogan IP Address is not the same (and not NAT). If users need help finding why that is, they are to asking for help doing so.
