C ONFIGURING TCP/IP P ROTOCOL
The iAN-02EX ATA has two modes of operation to communicate from a PC to
the iAN-02EX ATA:
■ Gateway Mode
■ Bridge Mode
The factory default mode is Gateway mode. After the PC is properly configured,
the ATA can be accessed with the procedures listed in Web Browser
.
Gateway Mode To communicate and configure iAN-02EX, the PC on your LAN must install
TCP/IP protocol. Make sure that the TCP/IP protocol of the PC is configured for
Obtain IP address from DHCP and is connected to the ENET (Ethernet) port of
the ATA. In doing so the PC obtains an IP address of 172.25.25.2 from the
iAN-02EX.
The iAN-02EX assumes an IP address of 172.25.25.1 without network
connectivity. This IP address is used for communicating with the iAN-02EX via
the Web UI or Telnet, with the PC connected to the ENET port.
The iAN-02EX assumes a DHCP IP address on the WAN side if connected to
the network. In this case user can communicate with the same IP address
172.25.25.1 with PC connected to the ENET port. PC in the network can
communicate with the DHCP IP address allocated to iAN-02EX.
Following the procedures below to configure TCP/IP protocol for Windows 2000
