When an IP address is set as an identical network segment by equipment with more than 2 Ethernet ports like
SP5000 series, it can't sometimes normally communicate.
For example when a subnet mask and an IP address are set as follows, LAN1 and LAN2 will exist in the same
network segment, it can't communicate in some cases.
Such as changing LAN2 to IP address :192.168.
2.1 (subnet mask :255.255.255.0) in a case like the above,
please make it a different network segment.
