This is my setup. I have ether1 and ether2. ether1 has dhcp-client set up and is connected to the cable modem (this works and I am connected to the internet).
ether2 I want to connect to a switch which again which again is connected to two computers. I’d like a DHCP server set up on ether2 so that the computers behind have a local ip and are also connected to the internet.
The problem is that ether2 is not giving out ip’s to the computers connected. I have followed these instructions: http://www.mikrotik.com/testdocs/ros/2.9/ip/dhcp.php (point 1-3), so basically:
/ip pool add name=dhcp-pool ranges=172.16.0.10-172.16.0.20
/ip dhcp-server network add address=172.16.0.0/12 gateway=172.16.0.1
/ip dhcp-server add interface=ether2 address-pool=dhcp-pool
Have I forgot something? Do I have to manually specify that ether2 should have ip: 172.16.0.1?
If I get this to work, how will ether2 understand that it needs to go to ether1 to access the internet? Do I need to bridge ether1 and ether2?
I finally got the setup up and running. For people who work with this every day, I guess it’s pretty obvious: I needed to add a static IP to ether1:
/ip address add address=172.16.0.1 interface=ether2 netmask=255.255.0.0
After this I got an ip address from the dhcp-server set up on ether2.
So now I need to get ether2 to understand that ether1 is “the way to the internet”.
hilton recommended that I use src-nat (masquerade) (which I do not know what is), so I tried the bridge alternative instead. This “kinda” work: the computer connected to ether2 could now browse the internet, however its ip address was now given from my dsl provider (dhcp-server seemed to have been dropped…).
So I guess this is why hilton recommends src-nat (masquerade)…could someone give me a brief explanation of what this is? Is this a correct tutorial for my setup?
