OSs supporting 'Automatic IP Addressing ', might initially not
establish IP connectivity with the STPro . This is because the IP
address they assimilated is not within the STPro 'Auto DHCP'
server range.
To prevent this problem, please power on your LAN devices
after the STPro has come online .
Indeed, when the STPro is in 'Auto DHCP', it will first operate as a
DHCP client. After the client timeout exceeded, it switches to DHCP
server mode, but this might be to late as some clients will already
selected an automatic IP address.
Dynamic IP addressing is a feature allowing DHCP clients to
assign themselves an IP address.
This happens when there is no DHCP server on the network, or
when the server is temporarily down. After automatic assignment,
the DHCP client will issue DHCP requests at regular instances.
If the DHCP server is back online, the client will now lease an IP
address from the server, after discarding its temporary automatic
IP address.
