Hello, just trying to understand whats going on with my traffic and ip tables.

When I check my router traffic, there are three addresses coming up in my list; the router address, the modem address, and then a third address which I am concerned about which is nothing like the other two.

Under "UDP/TCP" it says "unknown" and it has no status under "state"

I tried to block it with iptables, but when I go to check iptables it just spams:

I can't seem to block the ip with iptables at all.

I'm concerned about my networks being tampered with. Is this something I should be concerned about?[/quote]

There is not enough information here for us to help you... what router do you have and settings? What is the ip address

It would also be helpful if you posted the actual iptables rules you added / inserted, etc. We cannot see what is on your side of the screen unless you post it and we do not read minds.
