To set IP address on the device is correct. However, there are a few things to observe:
- device IP address has to belong to same IP subnet as router. E.g. if router has address 192.168.88.1/24 (default for Mikrotik), device can have any address from range 192.168.88.2-192.168.88.254. Be sure to use correct network mask (/24 in default case) and to set correct address for default gateway (use your Mikrotik’s address). Also don’t forget to set DNS server address (you can configure your Mikrotik to act as DNS resolver).
- it is wise to set device an address which is outside of DHCP address pool used by DHCP server on the router. While it would work even if used address is inside DHCP address pool, there is slight possibility for IP address clash in this case.
- device with static address set will not appear anywhere on Mikrotik. You will be able to see it if there are some connections going on in the list of connections (in WebFig that’s under IP->Firewall->Connections)
