IP Address Assignment Conflicts
Case D: Two or more subscribers have the same IP address.
By converting all private IP addresses to the WAN IP address, the VSG allows subscribers with different network
configurations to access the Internet. However, there are situations where two or more subscribers are using the
same private IP address. This may happen when a subscriber is configured to use a static (or fixed) IP address that
is the same as the IP address the VSG DHCP server assigns to another subscriber acting as a DHCP client.
In this case, the subscribers are not able to access the Internet.
