Looking inside the log, discovered interesting things, which ASUS must answer.
A lot of unknown IP-addresses appeared during booting of router.
IP's addressed by router firmware.
I tested them.
Seems that router.asus.com leads to unauthorised access to other owners of Asus routerswho authorised WAN access to their routers.
I attach more screendumps.
And ASUS engineers must answer and correct these critical security flaws.
Not naming that trying to connect a network printer via LAN, it gets an IP address for about 20 seconds, then gets disconnected.
Waiting for ASUS to address these problems!
