Hi, as part of routine security checks I recently portscanned all my home routers. On all my routers except my ASUS AC-66U only 2 essential ports were open on the LAN side and none on the WAN side. On the ASUS router, *A LOT* of ports were open on the LAN side, most of them apparently...

9998/tcp open distinct32
I have set it not to allow access to the admin interface on the WAN side but the port appears...
