[malpa]

Hi there

I am trying to block snmp incomming traffic from ip "xx.xx.xx.xx", using iptables but i dont understand why it is not done by the operating system REL.

trying with this

iptables -A INPUT -s 10.250.2.235 -p udp --destination-port 162 -j DROP
iptables -A INPUT -s 10.250.2.235 -j DROP


any comments

Thanks a lot

Hi there

Question
It could be that the comment shadowed in red color, is the issue ??

systemctl status iptables.service
● iptables.service - IPv4 firewall with iptables
Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled; vendor preset: disabled)
[highlight #EF2929]Active: inactive (dead)[/highlight]

Must I run "service iptables restart"?



Thanks a lot
