Hello,
I just noticed this message in my TG 585 v7 modem log.
ALG Protocol: UDP Open port: 7648 Helper: CU/SeeMe => ok
Can anyone tell me what it means please ? Is it a security breach ?
I don't use the CU/SeeMe software and it's not installed on my machine. I have Windows 7 firewall turned on and my modem's firewall is set to "standard".
Also what does "Use Extended Security" in the "Game and Application Sharing" page mean ?
I tried to disable UPnP and the modem restarted ? How come ?
Thanks in advance for the replies.

I found the following information from a PDF document titled "Thomson Gateways and UPnP".
UPnP Features
To summarize what has been explained in the previous chapters, a UPnP Internet Gateway Device allows you
to:
- Connect/disconnect the Internet connection.
- Create NAT entries.
- Get statistics about the Internet connection, from a remote interface.
Extended Security (default setting) - UPnP is enabled with the following limitations:
- Write mode option “NAT only”: only NAT actions are allowed remotely (i.e. creation, deletion). The
gateway cannot be connected/disconnected via UPnP. - Safe NAT option “enabled”: A control point can only create NAT entries for himself onto the gateway
device (e.g. not possible to open a door towards an other device available inside the LAN).
