Setting Up Mikrotik Hotspot Server

For your information , Mikrotik is a router os with all in one solution for small business and solution for your small  or Big Network. Mikrotik Router OS or Mikrotik Router Board can be used and setting as a Hotspot gateway with a login page. In this tutorials i will saw you how to configure Mikrotik as a Hotspot network with Login page and user manager . This is just a basic configuration, in the next article i will guide you to setting up the mikrotik as a hotspot with fully fiutured intergrated system.

For the first , make sure your router is have been installed this package :

System
DHCP
Wireless
Hotspot
Proxy
User Manager
Security
Advanced tools

Step to setting up Mikrotik hotspot :

system identity set name=MyNet
ip address add address 192.168.1.2/27 interface=ether1
ip address add address 192.168.0.1/24 interface=ether2

add comment="" disabled=yes distance=1 dst-address=0.0.0.0/0 gateway=\
192.168.1.1 scope=30 target-scope=10

[admin@MikroTik] > ip hotspot setup
hotspot interface: ether2
local address of network: 192.168.0.1/24
masquerade network: yes
address pool of network: 192.168.0.2-192.168.0.250
select certificate: none
ip address of smtp server: 0.0.0.0
dns servers: 8.8.8.8
dns name: hotspot.mynet
name of local hotspot user: user
password for the user: password

Now, we will configure the user manager :

tool user-manager customer add login=admin password=password
tool user-manager router add ip-address=127.0.0.1 shared-secret=12345 subscriber=admin
radius add service=hotspot address=127.0.0.1 secret=12345
ip hotspot profile set 1 use-radius=yes

Done, your Mikrotik now can be use as hospot gateway !!

Auto Flush Mikrotik DNS

A MikroTik router with DNS feature enabled can be set as a DNS server for any DNS-compliant client. Moreover, MikroTik router can be specified as a primary DNS server under its dhcp-server settings. When the remote requests are enabled, the MikroTik router responds to TCP and UDP DNS requests on port 53.

/ip dns
set allow-remote-requests=yes cache-size=10240KiB servers=8.8.8.8,8.8.4.4

/system scheduler
add interval=1d name="DNS FLUSH" on-event=dnsflush policy=ftp,reboot,read,write,policy,test,password,sniff,sensitive start-date=apr/25/2017 start-time=04:00:00

/system script
add name=dnsflush policy=ftp,reboot,read,write,policy,test,password,sniff,sensitive source="/ip dns cache flush"
