Hi all! 
Could anyone help me in right direction. 
I got RigPi to run within my home network. I try to open the ports in Teltonika 950 router but they are closed. I have an DYNDNS account inserted in the router. 
In RigPi I have WAN IP 94.191.141.133 
I have above in my dyndns acount. But I can not opened any port and not reach it.
