The correct title should be 2 NAS in 1 Network.
2 NAS in 1 Computer System sounds like you want to build two VM NAS in one computer.
For your question, dds ching has answered you. You have to set a static IP for your NAS in your router's dhcp server. Also, it is suggested to exclude the static IP in the DHCP server range.
For example, if you set the two NAS IP as 192.168.200.30 and 192.168.200.39, your DHCP server IP range should be 192.168.200.40-192.168.200.199 |
