Mikrotik Routerboard configuration behind Cisco 2900 router  [SOLVED]

Sun Jan 03, 2021 7:51 am

Hello everyone

Hope the festive season and new year ushers in beautiful things.

I'm sorry it's a bit of a long one and i had to mask some information.

With that said, I am in a conundrum and need help. Our network guy left and I've been tasked with getting the house in order.
I do have a bit of background in networking but that's well over a decade ago.


Key Details:
*About 2,000 workforce mostly conntected via omnidirectional & sectoral WLAN
*A Cisco 2900 router and a Mikrotik RouterBoard were purchased
*DIA via microwave
*Connection should be ISP Minilink IDU, to Cisco Router, to Mikrotik RouterBoard and to end-users via LAN & WLAN
*Mikrotik is basically needed for Hotspot & user bandwidth-controlled logins.


ISP given addresses:
IP 1xx.xx.x.162
NM 255.255.255.252
GW 1xx.xx.x.161

ISP given DNS:
xxx.xxx.xxx.1
xxx.xxx.xxx.2


Summarily, I configured the Cisco thus:
#GE0/0 - 1xx.xx.x.162 255.255.255.252
#GE0/1 - 192.168.xx.1 255.255.255.0

#DHCP pool 192.168.xx.0 255.255.255.0

#Default Route 1xx.xx.x.162

#dns-server xxx.xxx.xxx.1 xxx.xxx.xxx.2

#excluded 192.168.xx.1 192.168.xx.10

#GE0/0 nat outside

#GE0/1 nat inside (also source list & overloaded)

#ip route 0.0.0.0 0.0.0.0 1xx.xx.x.161

It's been a while since I did this but I believe it's ok (corrections will be appreciated if otherwise)


My challenge is Mikrotik.
I've gotten a refresher and i believe setting up hotspot, profiles and users won't be an issue rather IP addressing, DHCP and NAT as there may be a double/conflict with Cisco.


So, I configured the Mikrotik thus:
eth1: 192.168.xx.2
eth2: 192.168.1. 1/24


DHCP client: eth1


Routes:
Destination 0.0.0.0/0
Gateway 192.168.xx.1 i.e., IP of GE0/1


NAT:
Source 192.168.1.0/24
Destination 0.0.0.0/0, Action Masquerade


DHCP Server Using Dhcp setup:
Int 2
Address 192.168.1.0/24
Gateway 192.168.1.1(IP of Mikrotik)
Address to give out (192.168.1.2, 192.168.1.254)
DNS servers (192,168.1.1, xxx.xxx.xxx.1, xxx,xxx,xxx,2)



NAT:
port-forwarding using netmap on port 80.

END

That's it with Mikrotik and like i said, hotspot, profiles and users won't be an issue But I really need help on the others.

Thanks

Yes, thanks so much for your help.

Settings were in order but had to change my pool from a class 24 to class 16
