MN 700 Ports open

When I run internet security tests they tell me ports 80
and 21 are open. How do I close them and how did they get
opened. I can find nothing about ports in the MN700 set-up
program.
TIA

Verify also you have not turned off the router firewall
or open the DMZ.

Otherwise, redirect them to a non-existing IP. On the LAN
menu reserve one IP from DHCP, and use it to forward
ports 80 and 21. This should prevent them from opening.

Since I do not have a MN700, cannot say why the ports are
opening. I had that kind of behavior on a MN500 with an
earlier firmware. Port 80 would automatically open when
running a web server, although I had no port forwarding
set. Another reason the port may open *may* be
programmatically by software -- it should show the port
opening in the router logs in this case.

If you are not running a web and/or FTP servers, I would
suggest running a virus check and look for troyans and/or
malware on the system.

Could you be a bit more specific in your instructions? I
can not tell where and to what I am supposed to do your
suggestions.

Hi, I had the same problem. Apparently people were somehow
gaining access to my testing IIS server, utilizing buffer
overruns, messing around with security permissions, you
know, the usual..

Anyway, I ran security tests and found that port 80 was
detectable as its status was set to closed rather than to
stealthed in all those tests.Also, apparently, if I use
application port forwarding those ports become visible
too.


I have the MN-500 router too. How do you set up a non-
existing IP? I can't figure out how to do it.

Hey, I figured it out. Don't bother about the whole lan
menu thing. Just go to persistent port forwarding and
forward port 80 and port 20 to an IP address that doesn't
exist in your network. Try the lower numbers, those work.
I redirected the ports to IP 192.168.2.5 (of course you
may have a computer at that port so don't necessarily
forward requests there).

Hope this helps!
