Perform the tasks below to set up DHCP for the tenant.

  • A DHCP helper/relay is required to deliver the DHCP requests over the VPN tunnel to the tenant network. This can be done directly on the switches to which the hosts are attached or if not possible, a small Linux appliance can be configured in the tenant to perform this function.

  • Configure the DHCP scope for the desktop subnet, starting at x.x.x.30.

  • Configure DHCP option code 74 (IRC Chat) to point to the two IPs allocated for the tenant appliances. For example, if you are using a Windows server to provide DHCP service:

    1. Open the DHCP configuration client from Control Panel > Administrative Tools.

    2. Right-click Server Options and select Configure Options from the pop-up menu

    3. If you have defined limited address scopes, you can confine the options configuration to a particular scope. Click on the scope and right-click on Scope Options to configure the 074 option code for that scope only. Configuration is the same as for the whole DHCP server.

    4. Scroll down to the 074 option for Internet Relay Chat (IRC) and check the box.

    5. Add IP addresses for tenant appliances.
