Thomson/ Technicolor aficionado please- port closing help

Prior to PN, I was using Sky with their router. I noticed no entries in the router log trying a brute force attack, neither did I know about Shields Up for testing either. Upon moving to PN, I used the 582n which is set up basically by PN with their firmware. I never saw any intrusions into the logs on that device. As soon as I used the new Tg589v3, I am inundated with attacks from various Asian ip addresses.
You can see from the previous post some of the solutions proffered me, but none appear to work and I don't really want upnp off unless I really have to. I am hoping there is some Technicolor bod out there that will be able to explain to me in "Noddy" terms what I need to do to stealth port 22 please. This port is open by default out of the box as I have reset the router with nothing attached to it and Shields Up still finds it.
Thank you in advance anyone taking the time to read this.

Quote from: Marksfish I downloaded putty and got access to 22, but don't know the password as I haven't set one up, so not sure where to go from there.
I think it will be the same username and password hat you use to access the router's setup webpages. I didn't think it is possible not to have one, either there's the default username and password, or it prompts you to set one when you first enter the details it needs to connect to Plusnet.

So being able to access it, means it needs to be shut somehow.

Well yes and no !
It is one thing for you to be able to access the router using SSH from your LAN, and that is normal.
The problem you have is that somehow your router is allowing SSH to be accessed from the WAN (internet) port !,
and it is this external access that you need to prevent.
That is why I suggested setting up a port forward to a non-existent LAN IP address, as that should redirect the router's external SSH port to somewhere other than the router's WAN interface.

After connecting to the router using SSH, please enter the following command and post the output.
:service system list

Quote from: Marksfish Sorry, not sure how to format the output:
The simplest method of formatting that sort of text is to use the '#' (Insert Code) button above the forum text entry box.
When you copy and paste the text, immediately before you paste, press the '#' (Insert Code) button, and then paste the text.
It will then come out like this -

:service system ifadd name=SSH group=lan
Followed by
:saveall
to save the configuration.
Then re-check if port 22 is open at http://canyouseeme.org/ or the GRC Shields Up website.

Quote Your system has achieved a perfect "TruStealth" rating. Not a single packet — solicited or otherwise — was received from your system as a result of our security probing tests. Your system ignored and refused to reply to repeated Pings (ICMP Echo Requests). From the standpoint of the passing probes of any hacker, this machine does not exist on the Internet. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system wisely remained silent in every way. Very nice.
Thank you to everyone that took the time to try and help me with this issue, on this thread and the other. Just the webcam port open now, i'm happy with that.
