Hi. To avoid DDoS attacks I updated my Debian from 7 to 10 and now I'm going to re-write my old iptables. Are that good and correct or can someone suggest me better ones?

My current iptables:
https://forums.alliedmods.net/attach...8&d=1610297326

The most common attacks types:

2021-03-13 14:57:48 - anomaly incoming UDP 89280 pkts/s
2021-03-12 22:031 - anomaly incoming DNS 16927 pkts/s
2021-03-11 20:48:53 - anomaly incoming DNS 76677 pkts/s
2021-03-11 18:40:28 - anomaly incoming NTP 12039 pkts/s
2021-03-08 193:24 - anomaly incoming DNS 21941 pkts/s
2021-02-01 22:15:56 - anomaly incoming NTP 61595 pkts/s
2021-01-25 21:189 - anomaly incoming NTP 221578 pkts/s

VPS's parameters:

4 vCPU
16 GB (using 1.41 GB)
160 GB SATA (Inode 5%)
100 Mbps (up to 16 TB/mėn.)
0.36 TB = 0.02 TB (in) + 0.34 TB (out)

Thank you.
