Hi!
Sorry for talking in english, my Dutch is really bad.
I have noticed that recently, while in game (league of legends) I was having sudden ping changes. Checking in the security log of the router, I can see a lot of lines like this:
3 Dec 31 17:48:04 kern alert attack kernel: [10638173.547262] UDP_FLOODING ATTACK:IN=eth1.3 OUT= MAC=10:71:b3:81:e5:af:00:0e:00:00:00:04:08:00 SRC=159.196.236.230 DST=(my public IP) LEN=132 TOS=0x00 PREC=0x00 TTL=53 ID=40515 PROTO=UDP SPT=6890 DPT=24152 LEN=112

From what I can understand, these outside IPs are pinging my router, they happen in sudden spikes from several IPs. Anything I can do about this? I cant see anything in the router options to block these IPs, I have a Zyxel EX5601-T1. DDoS protection is on by default also.
Thank you in advance!
