Ports listening on G3100 router?

Message 1 of 3

I ran an nmap scan against my G3100 router and came across the following results.  Anyone know what the services are that are running?

 

-----

Nmap scan report for G3100.myfiosgateway.com (192.168.1.1)

Host is up (0.0018s latency).

Not shown: 65528 closed ports

PORT      STATE    SERVICE

53/tcp    open     domain

80/tcp    open     http

443/tcp   open     https

1990/tcp  open     stun-p1

4577/tcp  filtered unknown

39543/tcp open     unknown

46413/tcp open     unknown

MAC Address: B8:F8:53:56:70:AA (Unknown)

 

Nmap done: 1 IP address (1 host up) scanned in 7.30 seconds

-----

 

tcp/53 is likely related to DNS and both tcp/80 and tcp/443 are likely the management interface.  Any thoughts on the other listening ports?

Not sure why you are interested at the ports. If you are very conscious of the security, I suggest you to buy a security gateway.

 

Some ports are Verizon diagnostics for STBs, MoCA devices and extender.

 

Some ports can be triggered to open by the request of an internal device.

Confirming what the other user said - not sure about the 1990 but the other higher ports are for STB/DVR etc.. here's some info on that - https://www.dslreports.com/faq/16710
