Port Filter

[Lacho]

Видях го в един италянски сайт

и съм го направил така мисля, че ще е полезно:

/ ip firewall filter

спъва лан портове няма шерове няма игри има недоволни

но това лично решение

това би вършило по добра работа

Drop port scanner

/ip firewall filter add chain=input protocol=tcp psd=21,3s,3,1 \

action=add-src-to-address-list address-list="port scanners" \

address-list-timeout=14d comment="Port scanners to list " disabled=no


/ip firewall filter add chain=input protocol=tcp tcp-flags=fin,!syn,!rst,!psh,!ack,!urg \

action=add-src-to-address-list \address-list="port scanners" address-list-timeout=14d comment="NMAP FIN Stealth scan"


/ip firewall filter add chain=input protocol=tcp tcp-flags=fin,syn \

action=add-src-to-address-list address-list="port \scanners" address-list-timeout=14d comment="SYN/FIN scan"


/ip firewall filter add chain=input protocol=tcp tcp-flags=syn,rst \

action=add-src-to-address-list address-list="port \scanners" address-list-timeout=14d comment="SYN/RST scan"


/ip firewall filter add chain=input protocol=tcp tcp-flags=fin,psh,urg,!syn,!rst,!ack \

action=add-src-to-address-list \address-list="port scanners" address-list-timeout=14d comment="FIN/PSH/URG scan"


/ip firewall filter add chain=input protocol=tcp tcp-flags=fin,syn,rst,psh,ack,urg \

action=add-src-to-address-list \address-list="port scanners" address-list-timeout=14d comment="ALL/ALL scan"


/ip firewall filter add chain=input protocol=tcp tcp-flags=!fin,!syn,!rst,!psh,!ack,!urg \

action=add-src-to-address-list \address-list="port scanners" address-list-timeout=14d comment="NMAP NULL scan"


/ip firewall filter add chain=input src-address-list="port scanners" action=drop \

comment="dropping port scanners" disabled=no[/code]




и това изглежда хубаво ама какви проблеми създава не е истина
