I have just run the tests on grc.com and port 21, although closed, is not stealthed. I have got Windows Firewall turned off, I'm using Comodo. However, I think it is the router's firewall settings that need to be changed, but they seem to not be editable. Can anyone tell me how I can stealth port 21 ftp? I am using the Technicolor TG582n.
Thanks

Could you post the result of this telnet command from your router here?
:service system list expand=enabled
This will allow us to review the configuration of the router services and see if one is misconfigured.
Thanks,
Matt

This command will disable the FTP server on the router. I'm not sure why the FTP server is sending TCP reset packets to request from the WAN interface (assuming this is what it is doing...), I've got the FTP server enabled on my TG582n (but just on the LAN interface as yours is) and the packets are dropped silently.
:service system modify name=FTP state=disabled
Let me know if this fixes the issue.
Thanks,
Matt

Thanks for your help so far. I tried your suggestion, but grc.com still reports FTP port 21 as closed but not stealthed.

In telnet, :service host list gives the result FTP Server host = 192.168.1.253 Server.
What would be the security and useability ramifications of typing
:service host disable name="FTP Server"
Thanks for your time and help so far.

This has stealthed the port, but I'd like to be sure that it is the correct command to put in to do this securely.
Thanks.

Service Host is where port forwarding rules are set up. It looks like port 21 is forwarded from the WAN IP to LAN IP 192.168.1.253.
I'll check with Technicolor and see why this is.
Thanks,
Matt

The command you ran will probably prevent this from being accessible on the WAN if you ever chose to set it up.
You've fully disabled it with the command you ran.
Thanks,
Matt
