Blocking web in mikrotik

This example will explain you “How to Block Web Sites” & “How to Stop Downloading”. I have use Web-Proxy test Package.First, Configure Proxy.

/ip proxy
enabled: yes
src-address: 0.0.0.0
port: 8080
parent-proxy: 0.0.0.0:0
cache-drive: system
cache-administrator: "ASHISH PATEL"
max-disk-cache-size: none
max-ram-cache-size: none
cache-only-on-disk: no
maximal-client-connections: 1000
maximal-server-connections: 1000
max-object-size: 512KiB
max-fresh-time: 3d

Now, Make it Transparent

/ip firewall nat
chain=dstnat protocol=tcp dst-port=80 action=redirect to-ports=8080

Make sure that your proxy is NOT a Open Proxy

/ip firewall filter
chain=input in-interface= src-address=0.0.0.0/0 protocol=tcp dst-port=8080 action=drop

Now for Blocking Websites

/ip proxy access
dst-host=www.vansol27.com action=deny

It will block website http://www.vansol27.com, We can always block the same for different networks by giving src-address. It will block for particular source address.

We can also stop downloading files like.mp3, .exe, .dat, .avi,…etc.

/ip proxy access
path=*.exe action=deny
path=*.mp3 action=deny
path=*.zip action=deny
path=*.rar action=deny.

Try with this also

/ip proxy access
dst-host=:mail action=deny

This will block all the websites contain word “mail” in url.

Example: It will block www.hotmail.com, mail.yahoo.com, www.rediffmail.com

ENJOY BLOCKING…….

Bloking Mikrotik dari Scan Winbox dan Neighbour

Kadang kala para ISP atau penyedia jasa layanan tidak terlalu jeli untuk melindungi customernya. Terutama ketika melindungi router pelanggan yang menggunakan Mikrotik RouterOS(tm). Dengan menjalankan IP >> Neighbor kita bisa melihat router mikrotik lainnya yang secara fisik terhubung dengan router kita melalui jaringan di provider kita.

Untuk itu kita bisa melindunginya dengan berbagai cara misalnya memblok scan dari winbox dan neighbor kita. Berikut adalah cara yang paling mudah :
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

Dengan perintah tersebut kita bisa menutup beberapa scan terutama yang menggunakan winbox dan ip neighbor. Port diatas adalah bagian dari share Mikrotik RouterOS yang memang di perlukan untuk monitoring.
