Attacking to my router (bln2) Urgent

[Chapulin]

Anyone is attacking my router (bln2).

The bln2 is core router of my net and send traffic (0.0.0.0/0.0.0.0) to internet router. In middle those router i have a firewall. The routes are statics

At 20:35 I lost the conection to internet and when reboot the bln2 or disconnect the cable (link) the conection (3 min) to internet back.

Ever at 20:35 this do it.

I put a sniffer with mirror port but there isn't nothing (i think)

Anyone can help me ?

Check your outside interface for traffic. I believe you should be able to do a snap on the statistics, though I forget the exact command.

Can you call your service provider to confirm your connection is up?

Why do you think you have someone attacking you? I'm not sure I understnad your reasoning if the only problem is your inability to get to the net.
