Hey.
Tryng to get Remote management to work, but are having some problems with it.
Firmware version 3.14.3 Build 15.05.18. Rel 70901n
Hardware Version WDR4300 v1 00000000
Im on fiber with 75/75 speed, so i have a box to recive the signal, and its external IP 254.213.213.51 (Exampel)
And the WDR's wan adress 100.222.213.19 (Exampel)
Because i dont know what my ip is(yet, for the remote computer) to control the WDR remotely, i have set it up to 255.255.255.255
But do i need to route? port forward? or anything to be able to access the WDR. maybee even a no-ip account ?
I have tried to acess it, from my phone with wifi disabled, but no luck...

Could anyone please help explain HOW to set this up correctly. and please stepwise, in a way so a kid could understand it,
english is not my native language, ;)

Please help.
Thanks in advance
Warley
