RouterOS Beginner Basics
1

Hi , so far I had " mikrotik OS " on one old computer. But now I buy this one " RB751U-2HnD" , and problem start :slight_smile:

This was my configuration on OS , and worked.

"
ip address add address=192.168.1.137/24 interface=ether1
ip route add gateway 192.168.1.254
ip firewall nat add chain=srcnat action=masquerade out-interface=ether1
dns with - winbox
ip > dns > settings > primary 192.168.1.254 - allow remote requests
ether2:
ip address add address=192.168.10.254/24 interface=ether2
ip pool add name=dhcp-pool-1 ranges=192.168.10.2-192.168.10.200
ip dhcp-server add name=server disabled=no address-pool=dhcp-pool-1 interface=ether2 lease-time=1d
ip dhcp-server network add address=192.168.10.0/24 gateway=192.168.10.254 dns-server=192.168.10.254

"
I have 3 lan cards and 1 wifi , and lvl4 licence.

This work good so far..
My “ether1” lan1 receive internet from my router " 192.168.1.254 " , and send to ether2 whitch is lan2 bridged with lan3 and wifi .

so my all computers are connected to lan2-3-wifi.


now problem :

I take this “RB751U-2HnD” and reset him to zero. now have eth1,2,3,4,5 and wifi. ( I dont use poe ). I try with same configuration like on OS , but not working. try to jump to Eth2 to be first and internet exit to Eth3, but still not working…

Is there anything wrong with my configuration for RB751U-2HnD ? :wink:

regards

Have you delete the defaulth configuration after reset?

3

ya., all reset to start inside rb751… ( reset + delete all configuration to zero )

when reset have " ether1,2,3,4,5 and wifi " … and I wanna to ether1 be " wan " , ethernet 1 receive internet from my adsl router (192.168.1.254) ,and ethernet 2,3,4,5 and wifi send internet with (192.168.10.254)..

so now I have back my OS mikrotik what working good. and my computer is 192.168.10.110 , dns and getw 192.168.10.254 ( mikrotik )

4

Connect ether1 to the adsl modem set ether 1 as dhcp-client
Make abridge and add ports eth2, eth3, eth4,eth5 and wifi
Give bridge ip-adress and configure the dhcp server on it
In firewall configure nat.

5

not working :frowning:

on my computer 192.168.10.110 , I can reach in RB751 with winbox , but no internet.

or " WAN " cant be ether1 ? I put cable from adsl (192.168.1.254) to Ether1 (poe port ).
I put static address on Mikrotik 192.168.1.5 and gateway 192.168.1.254

on bridge or ether2 I try put 192.168.10.254 ( that must be internet exit but with control of Mikrotik ) , but not working…
any more ideas ? :slight_smile:

have you set firewall nat rule

scrnat = masquerade

Have you fil in the dns server by dhcp setup
Look if the cables good

By dhcp client are you connected with adsl modem

not working., in Nat., I also try put " out " ether1 - 2,bridge, etc.

Is it possible that " WAN " cant be port 1 ? ( port1 - Poe )

8

Try set the wan port to eth5 as dhcp-client

working on ether5 as Wan, and bridge ip 192.168.10.254 as exit for my computer :wink:.

thanks
