DHCP Server. The interface VLAN and gateway interface cannot be the same.
15.Define or override the Network Address Translation (NAT) direction.
Select either the Inside, Outside or None radio buttons.
• Inside - The inside network is transmitting data over the network its intended destination. On the way
out, the source IP address is changed in the header and replaced by the (public) IP address.
• Outside - Packets passing through the NAT on the way back to the LAN are searched against to the
records kept by the NAT engine. There the destination IP address is changed back to the specific
private class IP address in order to reach the LAN over the switch managed network.
• None - No NAT activity takes place. This is the default setting.
