Help needed - Firewall rules with D-Link DI-604


I have a D-Link DI-604 router, firmware version 2.18.

Yesterday, I noticed that some rules were added to my firewall configuration. There were 5 or 6 of them. The rules allowed, and redirected, incoming traffic to one specific computer in my LAN (Windows XP Professional). I don't remember all the ports involved but I think that they all had the same name : msmsgs ...

I reset the router, reloaded my initial configuration and changed all passwords. I also changed my log settings to add debug information.

On the Windows XP Professional computer, I plan to install Zone Alarm and hope it's going to help me understand what happened... because I have a feeling it is going to happen again...

Now, I am wondering how these rules got there? Remote management (http) was enabled but, as far as I know, only the administrator has write privileges... Right? I'm really no expert with these technologies. If anyone has any ideas or comments, they're more than welcome.

Thanks a lot, Nathalie.

Try disabling XP's messenger service.

Click Start, then Run, then type in: services.msc Go to the messenger service and set it to disabled (you might also want to change it from automatic to manual).

Don't install Zone Alarm -- update to Windows XP Service Pack 2, if not already done, and enable the Windows Firewall, and enable logging.

Some "remote" user connected to the web-interface, with the default password to the administrator ID, determined the IP-addresses that were active on your network, and made the changes. The intent of the changes was to allow remotely-initiated "pop-up" messages to "tunnel" through your router to your Windows XP system, and create annoying pop-ups. Nasty fellows on the Internet!!!
