Zdravim vsetkych,

dnes rano sa mi v security logu objavilo niekolko desiatok hlasok:
icmp redirect from 192.168.0.1: 192.168.0.110 => 192.168.0.110

0.1 je vnut. adresa ADSL routera
0.110 je vonkajsia adresa FreeBSD firewallu

Mam nastavene sysctls:
net.inet.icmp.drop_redirect: 1
net.inet.icmp.log_redirect: 1

Prosim, co sposobi tieto hlasky? Je s nimi spojene nejake riziko?

Vdaka,

Peter Rosa
