Dapat pecerahan dari siniServer Fault tetapi belum di coba.
Di dokumentasi dulu, siapa tahu nanti dipakai.
If you want to shut down multicasts on an interface completely, use
storm-control multicast level 0
switchport block multicast
The first command prevents inbound multicasts from entering the switchport. The second stops outbound multicasts from getting out.
Instan firewall yang mudah cara instalasinya.
Supaya saya tidak lupa dan bermanfaat buat yang lain, maka saya dokumentasikan saja :D.
Untuk trustix, dan “mungkin” distro lain yang tidak spesifik, sebaiknya ambil paketan “noarch”.
Bisa juga pakai versi tgz. Tapi saya lebih memilih yang rpm, biar ndak mumet. Namanya juga mau instant
Contoh kasus, shorewall akan dipasang di mesin mail dengan 1 interface, dan versi terbarunya 4.0.11

Hi, i created these 2 simple rules for firewall forward and this work very fine…… do not say it to anybody ;) :D
2 ;;; BLOCK SPAMMERS OR INFECTED USERS
chain=forward protocol=tcp dst-port=25 \
src-address-list=spammer action=drop
3 ;;; Detect and add-list SMTP virus or spammers
chain=forward protocol=tcp dst-port=25 connection-limit=30,32 \
limit=50,5 src-address-list=!spammer action=add-src-to-address-list \
address-list=spammer address-list-timeout=1d
When detect an infected user with a worm or doing spamming this rule add this user to a spammer list and block the SMTP outgoing for 1 day ;)
Regards!
Alessio
