Hello everyone,
I have created 2 bridges internally bridge 1 from eth 1-4 where i work with 169.254.0.0/16 devices , and bridge 2 eth 5- 8 where i work with 172.16.0.0/16 devices… My problem is that i don’t know how to make the 2 LANs connected on the same microtik and make them see each other. Do i need to create a static route, form another bridge that includes both, work on the firewall, work on the NAT issue. I’m trying them all by try and fail, can you please help me with this issue ?
You can’t bridge two bridges, just use one bridge then with VLANs (to separate access)
But you can route IP traffic between two bridges.
The problem with 169.254.0.0/16 is that this address space is IPv4 link local (also known as APIPA) which has no notion of default gateway. Which means that devices in that subnet don’t know anything about mikrotik device being router and since addresses are link-local, that’s the only correct way.
First make sure devices in both subnets receive proper IP settings, including IP address of default gateway. Then that gateway will route traffic between both networks (unless firewall setup on router prefents it).
After using MKX’s sage advice post your config.
