Connec two networks (routers) via LAN ports

I want to connect my two networks in a way that from [computer 2] I can access [Computer 1] and what is most important [PRINTER]. I have tried force microtik to connect to [192.168.1.1] network by setting up DHCP client but that didnt work.

My questions are:
It is even posible, because [192.168.1.1] is just basic router without much configuration available?
If it is possible I want to ask for some directions how to achieve this kind of connection.

Both of these networks [192.168.88.1] and [192.168.1.1] have separate internet connection.

I see you’re using the best network-diagram software ever! I also like it very much! :wink:

The easiest way - add a secondary IP address from the 192.168.88.0/24 network on the LAN interface of the Sagemcom. I don’t know that device, maybe it’s possible.

If you’re not able to do that, this should work:

  • add a couple of addresses from the 192.168.1.0/24 network in the ether1 interface of the RB411, for example 192.168.1.3/24 for Computer1 and 192.168.1.4/24 for the printer.
  • create NAT rules on the RB411:
    /ip fire nat add chain=srcnat src-address=192.168.88.248 dst-address=192.168.1.0/24 act=src-nat to-addresses=192.168.1.3
    /ip fire nat add chain=dstnat dst-address=192.168.1.3 act=dst-nat to-addresses=192.168.88.248
    /ip fire nat add chain=srcnat src-address=192.168.88.249 dst-address=192.168.1.0/24 act=src-nat to-addresses=192.168.1.4
    /ip fire nat add chain=dstnat dst-address=192.168.1.4 act=dst-nat to-addresses=192.168.88.249

I haven’t tested it, but it should work. If not, let me know, I’ll test it and maybe come up with something else.

Another way to do this is to set the MT to 1.99 as its default gateway, shut off DHCP and statically assign an IP to computer 1. Then as long as the subnet mask is 255.255.255.0, everything should be in the same subnet and talk to each other.

I used to run a similar setup when I had two internet connections and two consumer routers.

thanks, second options works perfectly

Happy to hear that. :slight_smile:
