DHCP Server
Discover
Select Discover to allow the 833IS to find any DHCP servers on the local network.
Specify
Select Specify to configure the IP addresses of the DHCP servers. Up to 4 DHCP
server addresses can be configured.
IP Address
To add a DHCP server, enter the address in the IP Address field, and click Add.
To remove a DHCP server, highlight the address in the IP address list, and click
Remove.
Lease Duration
This field specifies the length of time that the DHCP server will allow the 833IS to
use the leased IP address on behalf of the client. The range is 1 to 65535 minutes.
Longer lease times will increase the chances that the client can reconnect to the
833IS and get the same IP address. 
Reconnect Enable
Click on this check box to allow a dial in user to disconnect and then reconnect at a
later time and retain the same leased IP address. This feature requires that all dial in
users have a unique User ID. Note that if the client disconnects and the reconnect
time expires, the lease will end. Also, if the lease expires, then another user may
have been assigned that address.
IP Pool
You can set up a pool of IP addresses for dial in clients. The first available address
will be assigned to the client when a client connects. Typically, you would want to
have an IP address available for each simultaneous user that can dial in.
