4.4.1 LAN
It allows you to set LAN IP and Subnet Mask for LAN interface. A DSP IP address can be
configured for FXO/FXS application. You can also enable or disable DHCP Server and
configure related settings. The “Static IP Lease List” allows to program 32 entries to have
the fixed IP address for the specified devices. If needed, it can also configure the second
IP address and Subnet Mask for the LAN interface (Figure 4 -8).

4.4.2 WAN
There are two modes that you can give WAN IP address to IG7500: Static IP mode and
DHCP mode. You can also enable or disable Firewall.
Network Address Translation (NAT) allows you to share one public WAN IP address for
multiple computers on your LAN side. In IG7500, NAT is default enabled and is not shown
on the page to prevent it from being disabled.
This page shows the setting of WAN interface which is Static IP mode (Figure 4 -9).
