Help with dreampi

[Tanino]

Hello. Hoping not to be against forum rules I post my issue also here as it has been +7 days posted within support area without any response:

https://www.dreamcast-talk.com/forum/vi ... 42&t=14843

I'm not able to connect my dreamcast, on the internet, trough dreampi altough the modem seems to be recognised properly.
Line inducer also seems to be working fine and giving 18 volts at the line plug terminal going to my dreamcast (see picture). The modem is a Lenovo RD02-D400 USB 56K.
Also see some other pictures of my config.
This is what I get from sudo ./dreampi.py --no-daemon
