Dear all,
this afternoon my ISP (German Tele2) had activated my adsl account. They gave me a Thomson Speedtouch 858i cable modem, but, something is still not clear to me - maybe someone out has the same modem and knows if the following things are "bugs" or "features".
- "Inside" my network I see several services running on the 858 - at least one, let's say httpd is needed to configure the box. But:
$ nmap 192.168.1.254
Starting nmap 3.55 (
Well, this is "inside", i.e. the "LAN" side, but, it seems to me, that all these ports are visible from "outside" too. When I look which IP the router has in the internet and I check this too, then the same ports are open and accessible from outside. I consider this to be a security lack.
Is this normal? Can access from outside be disabled as known from Cisco / Linksys?
- Furthermore, it seems to me that there's no way to manually start and stop an internet connection. In the web based config menu you can start / stop such a connection, but in my experience the modem establishes a connection to the isp as soon as you plug in the dsl / telephone cable into the 858.
Is this correct? Or can the 858 be configured in the way that a connection is only set up when packets are passed to the 858i as the default gateway, and after a certain timeout where nothing is transmitted, the 858 stops the connection?
Thanks for any hint!
Best regards,
Markus
