Hello, I'm preparing a small VPN project.
I found on the internet a bash script that slows down vpn clients with the TC command ([login to view URL]), but this isn't enough, I want to develop it.
The idea is to:
a) block max up and download of VPN's client to 10mbit/s
b) reduce the number of packets per second to some reasonable value
c) prevent port/local network scanning and sending emails
a) I did this part myself already, you can check and tell me if its ok or something should be changed there
b) sometimes users trying to abuse the VPN service, and i receive notifications from VPS providers, that my network generates
example:
"the IP subnet [login to view URL] is automatically nulled due to excessive incoming network data traffic.
Amount of PPS: 351632
TOTAL Incoming 2.2 G bits/s"
or closed server due to 40 kpps UDP.
I don't know if its DDoS attack or what but it has to be blocked.
c) also i got some warnings about scanning local network:
Sun Mar 8 07:10:37 2020 UDP <my ip4> 56225 => [login to view URL] 2054
Sun Mar 8 07:10:37 2020 UDP <my ip4> 56225 => [login to view URL] 2054
Sun Mar 8 07:10:37 2020 UDP <my ip4> 56225 => [login to view URL] 2054
and sending spam via emails – looks like my 2 iptable rules don't help
iptables -A OUTPUT -p tcp --dport 25 -j REJECT
iptables -A OUTPUT -p tcp --dport 465 -j REJECT
