Appendix B
IP Address Assignment Conflicts
This appendix describes situations where IP address conflicts may occur. Subscribers with
duplicate IP addresses will not be able to access the Internet.
Scenario 1: The VSG is using the same LAN and WAN IP
addresses
The following figure shows an example where the VSG is using a WAN IP address that is the
same as the IP address of a computer on the LAN.
Figure 178
IP Address Conflicts: Scenario 1
You must set the VSG to use different LAN and WAN IP addresses on different subnets if you
enable DHCP server on the VSG. For example, you set the WAN IP address to 192.59.1.1 and
the LAN IP address to 10.59.1.1.
Otherwise, It is recommended the VSG use a public WAN IP address.
Scenario 2: The VSG LAN IP address conflicts with the DHCP
client IP address
In the following figure, the VSG is acting as a DHCP server. The VSG assigns an IP address,
which is the same as its LAN port IP address, to a DHCP client attached to the LAN.
Figure 179
IP Address Conflicts: Scenario 2
To solve this problem, make sure the VSG LAN IP address is not in the DHCP IP address
pool.
