Hello, I have made the connections of the node as follows:

1st I have put a fixed IP on the node.

2nd The first router (an asus I have put a fixed IP) I have opened the ports in the option "virtual server" internal IP address of the node, source IP address of the second router that is movistar. The two open ports with the 28967 and the two protocols TPC and UDP.

3º I have performed the same action in the movistar router, in the virtual server option I have opened the ports and I have put the IP address of the asus router activating the 6/ppp0.1 interface (the Internet one as I understand it)

4º I have created an account in NO-IP and I have added it in the Dynamic DNS option.

I think I'm doing fine for now, but adding the DNS address Name.ddns.org:port to the node program would that be fine? Do I have to pay for it to redirect with the port as well?

I could use some help thanks.
