Hi Jacobo,
I also tested SM1.7 OS last night, I am using SW AZ GTi mount,
Mount IP address issue same, when I go to port selector, every time it is showing mount's default IP 192.168.4.1. But I am using home router's WIFI.
I tried to save mount's config in Ekos with no success.
West East buttons reversed also happened in my setup. South/North are OK
