6. Click Save.
If you enable DHCP relay, you may need to create firewall access policies to
permit the DHCP traffic. The figure below shows that four access polices are
needed to allow DHCP relay from one VLAN to another. (The access policies
are necessary whether the client and server are in the same zone or different
zones.)
1. Client to Self — Permit bootps
2. Self to server — Permit bootps
3. Server to Self — Permit bootps
4. Self to client — Permit bootpc
Figure 2-38. DHCP Relay Access Policies
Some of these access policies might already exist:
■ If the client is in a management-access zone, you do not need to configure
policies 1 and 4.
■ If the server is in a management-access zone, you do not need to configure
policies 2 and 3.
■ If both the client and the server are in a management-access zone you do
not need to configure any firewall access policies.
