I tried to nmap remotely my TomatoUSB and get this result:

Is this list of ports normal?

I'm not really sure what those ports might be. What I'd check first, and maybe you already have are what do you set to be open? Places I can think of to look are under Administration->Admin access look at remote access options. Under port forwarding should really look at all tabs but particularly at basic and UPnP/NAT-PMP to see if this is enabled and programs are opening their own ports.

I worry about possibility of hacker access to my router. It is strange that another port scan from different location reported 0 open ports.

most of the port scan stuff is alarmist crap trying to get you to buy something.

just ignore it. especially anything to do with gibson research…

Not strange if UPnP/NAT is responsible as ports opened by apps come and go, did you check that?

Which console command will disable/enable UPnP/NAT-PMP?
