I am using it with mobile broadband from Swedish operator Telia and my speed is excellent (150Mbit/s down and about 100Mbit/s up) so that part works just fine.
However, I am not able to access my surveillance cameras or my fileserver from outside my local lan.
I can access my router locally via webpage as well as via Winbox.
I am not able to access my router externally from outside my local net when using Winbox.
I am suspecting 2 issues:
1. I have a public IP address from my ISP that is NATed (most likely)
(I just realized that my "Public" IP when using for example whatismyip.org is for example 217.213.yyy.xx and when I look in the router interface for the modem I see an IP-address that is completely different: 100.99.yyyy.xxx?!)
2. I have done wrong when configuring port forward. I used the quick config page to "open" / port forward port 6601 to my local IP address.
However, I am not able to access the fileserver and I get "Connection timed out".
My config below. I used the command
Code: Select all
export hide-sensitive file=mikrotik
Code: Select all
# sep/09/2021 15:45:10 by RouterOS 7.0.2
# software id = PJ8R-F8ZN

# model = D53G-5HacD2HnD
# serial number = <I have removed the serial no>

CASE CLOSED!
It was my ISP Telia that had configured it wrong.... After 3 calls to tech support at Telia that took me the whole day the 3rd person at their 2nd line tech support finally configured it right!
It works fine now and I can access my fileserver from outside of my local network.
