[SOLVED] Can't connect to ISP via VDSL2 SFP module

Thank you for replying.
Output of logread | grep ppp:

What strikes me as odd is the time. Last line was actually at 22:37:52. In Foris timezone is set as Europe/Berlin. As far as I know, non-matching time data is never a good thing.
Here’s the output of cat /etc/config/network:

config interface ‘loopback’

And these are my ISPs requirement:

Data VLAN 10 with IP-Distribution via PPPoE (PAP)
Voice VLAN 20 with IP-Distribution via DHCP
VDSL2 ITU-T G.993.2, Annex-B/-J
Vectoring ITU-T G.993.5 (> 50 Mbit/s)
VDSL-Profile 17A
VDSL-Profile 30A (> 50 Mbit/s)
Dual-Stack Lite nach RFC-6333
DHCPv6 Option for Dual-Stack Lite nach RFC-6334

Unfortunately, I cannot ssh to my TO. Process /usr/sbin/sshd -D is running and my PC is all set - I can ssh to my laptop and back. Yet ssh root@192.168.1.1 returns
