DHCP Gateway IP
Address Though the DHCP server usually also acts as the
Default Gateway of the DHCP client, the access
point allows you to define a different Gateway IP
Address which will be allocated as the Default
Gateway IP of the DHCP client. The DHCP client
will thus receive its dynamic IP address from the
access point but will access to the Internet or the
other LAN through the Default Gateway defined
by the DHCP Gateway IP Address.
For instance if the access point in Access Point
Client mode connects to an Internet gateway
X , a
PC wired to the access point will be unable to
obtain a dynamic IP address directly from
X . But if
you enable the DHCP server of the access point
and set the IP address of
X as the DHCP Gateway
IP Address, the PC will obtain its IP address from
the access point and access the Internet through
X .
DHCP Lease Time
This is the length of time that the client may use
the assigned address before having to check with
the DHCP server to see if the Address is still valid.
