Assigning static IP addresses to individual PCs
Even if you have activated the DHCP server, you can still assign a static IP address to
individual PCs (e.g. when setting up these PCs for NAT functions).
Enter the
MAC address
of the PC to which you want to assign a static IP address
and the
IP address
you wish to assign to the PC.
Configuring the local network in Bridge operating mode
In
Bridge
operating mode (
page 32) the SE681 WiMAX DHCP server is deactivated.
The network components get their IP addresses from a DHCP server in the public net-
work.
Ageing time for
MAC table
When a PC in the network is accessed, your SE681 WiMAX writes the
MAC address and port number in a MAC table to speed up further
accesses. The entry in the MAC table is deleted after a fixed time. If
necessary you can change this value via the
MAC table ageing time
parameter.
Protection
against DoS
attacks
DoS (Denial of Service) attacks are attacks on a system in the net-
work to make its services unusable. This is basically done by over-
loading the system by constantly sending requests. In Bridge mode,
the SE681 WiMAX provides protection against DoS attacks, which
you can enable or disable via the
activate DOS protection
parame-
ter.
i
Forwarding on busy
cannot both be activated in parallel.
