DHCP server — advanced options
Warning
1.
DHCP server cannot assign addresses to RAS clients connecting to the RAS server
directly at the WinRoute host (for technical reasons, it is not possible to receive DHCP
queries from the local RAS server). For such cases, it is necessary to set assigning of
IP addresses in the RAS server configuration.
2.
The RAS service in Windows leases a new IP address for each connection (even if re-
quested by the same client). WinRoute includes RAS clients in total number of clients
when checking whether number of licensed users has been exceeded (see chapter
This implies that repeated connection of RAS clients may cause exceeding of the num-
ber of licensed users (if the IP scope for the RAS service is too large or/and an address
is leased to RAS clients for too long time). Remote clients will be then allowed to con-
nect and communicate with hosts in the local network, while they will not be allowed
to connect to the Internet via WinRoute.
Declined options
These options define how declined IP addresses (DHCPDECLINE report) will be handled.
These addresses can be either considered released and assigned to other users if needed
(the Offer immediately option) or blocked during a certain time for former clients to be
able to use them (the Declined addresses can be offered after timeout option).
