How to give Internet to a device in the second Mikrotik local network?

Question

Mikrotik

There is a microtic, in the 2nd port of which a switch with devices with static types 192.168.100.1/24 is plugged. On the Mikrotik itself, the local network via dhcp with 192.168.88.1/24, the Internet comes to 1 port. It is necessary to give the device with ip 192.168.100.50 access to the Internet. Tell me how to do it? Also, all devices on the 192.168.100.1/24 network should see each other (this works as is). It turns out that you need to add a second local network on the port and release the device from it to the Internet and you need to see network devices 192.168.100.1/24 from the main Mikrotik network.

Answer 1

Trap plan
- pull out port 2 from the bridge
- plug a switch into the second port of the Mikrotik
- assign the address 192.168.100.1/24 to port 2
- configure it on a PC with the address 192.168.100.50 gw 192.168.100.1
- check the ping between 192.168.100.1 and 192.168.100.50
- allow on Mikrotik forward between networks 192.168.100.0/24 192.168.88.0/24
- allow on Mikrotik forward between networks 192.168.100.0/24 and WAN
- add a masquerade rule for 192.168.100.50 on Mikrotik
