What model D-Link router do you have?


* What Hardware version is your router? Look at sticker under the router case.
* Link>What Firmware version is currently loaded? Found on the routers web page under status.
* What region are you located?
* Are you wired or wireless connected to the router?

Internet Service Provider and Modem Configurations

* What ISP Service do you have? Cable or DSL?
* What ISP Modem Mfr. and model # do you have?
Check the IP address you see in the attack at domaintools.com to see where that IP address is coming from.

FurryNutz:
If you have the SPI firewall enabled then this is the router doing it's job and reporting whats happening in the logs. It's stopping the attacks.
You'll need to contact your ISP to see if they can help you block these from actually happening or move your modems IP address your ISP gives you to a different IP address. However the attacker could follow you.

Good Luck.

Commissar:
I already did, but they said its not attacker, its a something about firewall rules are so strict, so router is distraffic the ports..
so i dont know how to change the rules at firewall
