when external interface addres attack(kind of scan) ha port down
hi i'm security engineer in Republic of Korea
I had a disability a few days ago

There was some network scanning, but not enough to have an impact
and every scanning was blocked
But after that happened, ha1 port downed
It caused a disability The situation repeated for 3minutes

I don't understand external interface addres was attaked
even all traffic blocked
I wonder why the ha1 port is down
Thanks for all replies and have a nice day
