It is possible instead of configuring the Access Control Server IPs locally on the client computer to
distribute them via DHCP. 

The Access Control Server IPs the client computer received via DHCP are visible in the Advanced
Settings section of the Barracuda NG Access Monitor or the Barracuda NG Personal Firewall. Both
provide the functionality to delete the Access Control Server IPs, if necessary. 

If the client computers in the network are configured to obtain their IP address using DHCP, there is
the possibility to trigger a DHCP renew whenever the client computer is assigned a different VLAN.
This can be configured either on the Access Control Server forcing it on the clients, or on the client
computer itself.
