Smart SR516ac

Hi Folks,

I have a Smart SR516ac modem-router software version: 2.6.2.7. When I nmap (from WAN) my public IP there are some ports open beside the ones I manually open.

PORT    STATE SERVICE
21/tcp  open  ftp
22/tcp  open  ssh
23/tcp  open  telnet
53/tcp  open  domain
80/tcp  open  http
139/tcp open  netbios-ssn
443/tcp open  https
445/tcp open  microsoft-ds

Nmap done: 1 IP address (1 host up) scanned in 1.58 seconds

I read the manual but I can't find how to close these ports. Also I contacted the ISP provider technician and they said that issue is beyond they support.
There are some settings in Management/Access Control/Services that are disabled for the WAN (which is OK) and enable and greyed out for the LAN (also OK). I can not find any other settings. Nevertheless the ports are still open and I have no control over. I am thinking maybe some of you has this model and can share the experience.

I looked at the manual at https://help.sonic.com/hc/en-us/arti...odem_interface but could not find anything .....

Thanks so much J65nko.

Running nmap from your LAN is one thing. Running it from the WAN on your public IP# is another, and that's what you really want to see:
