Hi all
Sth I want to clarify:
1/
240.0.0.0/5 - Class E Reserved
248.0.0.0/5 - Unallocated
Sometimes I got it should /4 or /5 ?
240.0.0.0/4 - Class E Reserved
248.0.0.0/4 - Unallocated
2/ Can I block it in the firewall for
"255.255.255.255/32 - Broadcast"?
deny ip from any to 255.255.255.255/32
deny ip from 255.255.255.255/32 to any
3/ I got the following. ls it normail?
why there is connection to the broadcast address
tcp 0 1 202.64.230.8:33397
192.168.255.255:25 SYN_SENT
Deny TCP 202.64.230.8:33021 10.254.254.254:25
Deny TCP 202.64.230.8:57798 172.21.143.58:25
Thank you so much
