RE: block incoming snmp traps from ip


Hi there

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

systemctl status iptables.service
‚óŹ iptables.service - IPv4 firewall with iptables
Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled; vendor preset: disabled)
Active: inactive (dead)

Must I run "service iptables restart"?

Thanks a lot
