The DSA-3100 comes with three Authentication modes, namely NAT and Router (as shown
below).
1.) NAT mode: All outbound IP addresses (the addresses must belong to the network
connected to Authentication Port) on Authentication Port will be translated to the
IP address of WAN Port to proceed.
2.) Router mode: All outbound IP addresses on Authentication Port will retain their
addresses; DSA-3100 functions as a router in this mode.
