Re: 2Wire 3801HGV - ports open (even when I didn't open it) Only if you know the type of service it is running.
I found that TCP port 3476 is open on my 3600. Clearly, it is waiting for some data after connect. I just hope it is not a backdoor to access my LAN. Luckily, I have another router behind it to protect from this madness. But if someone hacked the 3600 and change its DNS, I am screwed. Maybe it is time to use a public DNS like 8.8.8.8.
Port 25 will result in immediate disconnect. |
