Limit Youtube Video Streaming from mikrotik

After we arranged the limit rapidshare, YM, and other now we arrange the limit to youtube

1.  Make http-video layer7-protocol

/ip firewall layer7-protocol
add name=http-video regexp="http/(0\.9|1\.0|1\.1)[\x09-\x0d ][1-5][0-9][0-9][\x09-\x0d -~]*(conte
nt-type: video)"

Avoided Spam SMTP From Virus

Many viruses that after infecting our computer will send thousands of emails through our computer went out. This was very damaging we, apart from finished bandwidth we, also very annoying from the side of this email recipient.

We could prevent this matter with firewall Mikrotik

Make 3 Rule in Firewall

1.  Firewall Rule
- Chain : Forward
- Protocol : TCP
- Dst. Port : 25
- Src. Address List : SMTP-EMAIL
- Action : Accept

2. Next Rule

- Chain : Forward
- Protocol : TCP
- Dst. Port : 25
- Action : add src to address list
- Address List : SMTP-EMAIL
- Timeout : 00:05:00

3. Next Rule

- Chain : Forward
- Protocol : TCP
- Dst. Port : 25
- Action : Drop

Avoided Port Scanner from Hacker

Posted by admin under MIKROTIK TUTORIAL

Avoided Port Scanner from Hacker

To avoid the Port Scanner action from Hacker, then we could arrange in firewall mikrotik, by means of :

1. Make Filter

/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=2w comment=”Port scanners to list ” disabled=no

2. Make Chain

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=2w comment=”NMAP FIN Stealth scan”

add chain=input protocol=tcp tcp-flags=fin,syn
action=add-src-to-address-list address-list=”port scanners”
address-list-timeout=2w comment=”SYN/FIN scan”

add chain=input protocol=tcp tcp-flags=syn,rst
action=add-src-to-address-list address-list=”port scanners”
address-list-timeout=2w comment=”SYN/RST scan”

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=2w comment=”FIN/PSH/URG scan”

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=2w comment=”ALL/ALL scan”

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=2w comment=”NMAP NULL scan”

3.  Drop Ip scanning

add chain=input src-address-list=”port scanners” action=drop comment=”dropping port scanners” disabled=no

Block Traceroute and ping from client

Posted by admin under MIKROTIK TUTORIAL

Block Traceroute

You could arrange him in firewall mikrotik, to avoid Traceroute and ping, Along With was the method that most was easy:

/ip firewall filter add chain=forward protocol=icmp icmp-options=11:0 action=drop comment=”Drop Traceroute”
/ip firewall filter add chain=forward protocol=icmp icmp-options=3:3 action=drop comment=”Drop Traceroute”

next you can block ping

/ip firewall filter add chain=input action=accept protocol=icmp limit=50/5s,2

Limit Bandwidth with extension in mikrotik

Posted by admin under MIKROTIK TUTORIAL

Apart from an administrator could arrange the limit bandwidth per clinet, a person admin could arrange bandwidth in accordance with extension that in download him, Along With was the method that most was easy:

/ip firewall filter add chain=forward \
src-address=[ip Local ] protocol=tcp content=.exe \
action=add-dst-to-address-list address-list=cekek \
address-list-timeout=01:00:00
/ip firewall filter add chain=forward \
src-address=[ip Local ] protocol=tcp content=.iso \
action=add-dst-to-address-list address-list=cekek \
address-list-timeout=01:00:00
/ip firewall filter add chain=forward \
src-address=[ip Local ] protocol=tcp content=.mpg \
action=add-dst-to-address-list address-list=cekek \
address-list-timeout=01:00:00
/ip firewall filter add chain=forward \
src-address=[ip Local ] protocol=tcp content=.mp3 \
action=add-dst-to-address-list address-list=cekek \
address-list-timeout=01:00:00

make mangel

/ip firewall mangle add chain=forward \
protocol=tcp src-address-list=cekek \
action=mark-packet new-packet-mark=cekek-bw

Now, You can Limit

/queue simple add name=download-files \
max-limit=64000/64000 packet-marks=cekek-bw

Block Scan Winbox and Neighbour Mikrotik

Posted by admin under MIKROTIK TUTORIAL

1. Block Scan Winbox and Neighbour Mikrotik

Apart from Protected router from the virus with configuration in firewall mikrotik , the network administrator also could protect router from scan winbox and neighbor. this was the matter that was important in the network, Along With was the method that most was easy:

copy and paste this script in console mikrotik

admin@mikrotik] interface bridge> filter print
Flags: X - disabled, I - invalid, D - dynamic
0 ;;; block discovery mikrotik
chain=forward in-interface=ether1 mac-protocol=ip dst-port=5678
ip-protocol=udp action=drop
1 ;;; block discovery mikrotik
chain=input in-interface=ether1 mac-protocol=ip dst-port=5678
ip-protocol=udp action=drop
2 ;;; block discovery mikrotik
chain=output mac-protocol=ip dst-port=5678 ip-protocol=udp action=drop
3 ;;; block discovery mikrotik
chain=input in-interface=ether1 mac-protocol=ip dst-port=8291
ip-protocol=tcp action=drop
4 ;;; block winbox mikrotik
chain=forward in-interface=ether1 mac-protocol=ip dst-port=8291
ip-protocol=tcp action=drop
5 ;;; block request DHCP
chain=input mac-protocol=ip dst-port=68 ip-protocol=udp action=drop
6 ;;; block request DHCP
chain=forward mac-protocol=ip dst-port=68 ip-protocol=udp action=drop
7 ;;; block request DHCP
chain=output mac-protocol=ip dst-port=68 ip-protocol=udp action=drop
2. Recorded all of IP scanner

To be able to router recorded all of IP scanner and afterwards was put into the IP Address list and was named in group “port scanner”, along with rule in firewall him:

- Script First

add chain=input protocol=tcp psd=21,3s,3,1 action=add-src-to-address-list address-list=”port scanners”
address-list-timeout=2w comment=”Port scanners to list ” disabled=no

- Script two

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=2w comment=”NMAP FIN Stealth scan”

add chain=input protocol=tcp tcp-flags=fin,syn
action=add-src-to-address-list address-list=”port scanners”
address-list-timeout=2w comment=”SYN/FIN scan”

add chain=input protocol=tcp tcp-flags=syn,rst
action=add-src-to-address-list address-list=”port scanners”
address-list-timeout=2w comment=”SYN/RST scan”

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=2w comment=”FIN/PSH/URG scan”

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=2w comment=”ALL/ALL scan”

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=2w comment=”NMAP NULL scan”

3. Script Three

add chain=input src-address-list=”port scanners” action=drop comment=”dropping port scanners” disabled=no’
