How to fix this issue. The computer1 is configured in the peplink balance580 with static IP and Mac Address. The computer2 is not registered in the peplink device then the IP is dynamic (change adapter setting is obtain). Per checking, the computer2 IP address is the same with the computer1 and the result was unable to connect or received internet connection of the computer1 due to IP conflict.
Typically I would keep all my static IPs in one group so 192.168.1.200-254 and then set DHCP outside of that range (192.168.1.10-199).
If you can’t do that, set a DHCP reservation in the Peplink for the statically assigned computers.
In theory you don’t need to as the DHCP server should check if there is a response on an IP locally before it offers it to the requesting device but maybe that check is not working.
