Hi guys,
Since post release annoucement V6.42.7 is locked I´m here to give you a feedback regarding my case there in order to contribute on the community.
After a new local CCR1009 reboot it started answering PING and HTTP access via LAN.
Also it was necessary rebuild the entire VPN L2TP/IPSec configuration following this guide --> https://manuth.life/l2tpipsec-vpn-serve ... -routeros/
Thanks everybody.
