Nonconfigurable DHCP Options

You cannot configure the following DHCP Options:

•Subnet Mask (option 1)

•Router (option 3)

•Domain Name Server (option 6)

•Domain Name (option 15)

•NetBios Name Server/WINS (option 44).

You configure these values on the central-site VPN Concentrator for the group to which the VPN 3002 Hardware Client belongs. As is the case for all group configuration parameters, the central-site VPN Concentrator pushes these values to the VPN 3002 over the tunnel.
