Dynamic firewall and dynamic host configuration protocol configuration

A method of dynamically provisioning virtual local area networks, comprising:

• obtaining, by a server, a first subnet interface information from a subnet interface pool in a configuration database and a first virtual local area network tag from a virtual local area network tag pool in the configuration database, wherein the first virtual local area network tag is randomly selected from the virtual local area network tag pool and is unrelated to, and randomly combined with, the first subnet interface information;
• provisioning, by a server, a first virtual local area network by transmitting the first subnet interface information and the first virtual local area network tag to a firewall device and to a first access device;
• obtaining, by a server, a second subnet interface information from the subnet interface pool in the configuration database and a second virtual local area network tag from the virtual local area network tag pool in the configuration database, wherein the second virtual local area network tag is randomly selected from the virtual local area network tag pool and is unrelated to, and randomly combined with, the second subnet interface information;
• provisioning, by a server, a second virtual local area network by transmitting the second subnet interface information and the second virtual local area network tag to the firewall device and to a second access device.

A method of dynamically provisioning a virtual local area network, comprising:

• determining, by a server, that a client device requesting a network service is a member of a group wherein members of the group are associated with a single virtual local area network tag;
• determining, by a server, that the client device is the first member of the group to request access to the network service;
• obtaining, by a server, subnet interface information from a subnet interface pool and the virtual local area network tag from a virtual local area network tag pool, wherein the virtual local area network tag is randomly selected from the virtual local area network tag pool and is unrelated to, and randomly combined with, the subnet interface information,
• sending, by a server, to an access device and a firewall device the subnet interface information from the subnet interface pool, the virtual local area network tag from the virtual local area network tag pool, physical interface designations, and instructions to configure a subnet interface using the subnet interface information and the virtual local area network tag and associate the subnet interface with the designated physical interfaces on the access device and the firewall device to provision the virtual local area network, and
• activating, by a server, the virtual local area network in response to receiving at least one message from the access device and the firewall device indicating that the subnet interface has been configured on each device and associated with the virtual local area network tag and the designated physical interfaces.
