11.3. ONLY ONE IP AVAILABLE FROM ADSL/CABLE SERVICE PROVIDER?
Sometimes only one IP address is available from Internet Service Provider (ISP) without NAT
router as the following figure. Usually, a DHCP or PPPoE server at the central side of ISP is used
to assign one IP address to each user. In this case, you may need to enable the embedded
NAT router of VS211 to provide more than one IP addresses for PC and VS211.
Example: To change PC IP address to the same subnet as 192.168.123.1 for VS211

property.

- The "Internet Protocol (TCP/IP) Properties" window will pop up.
