+### Leveraging 802.1Q Ethernet interfaces
+
+Due to technical limitations of bridge VLAN filtering, if a packet is ingressing
+to the bridge and has to access a layer 3 service running on the bridge, i.e.
+DHCP, the packet is untagged and then the outgoing packet is re-tagged with the
+set PVID value. Thus true separation cannot be achieved as we can only re-tag
+packets with one specific VID.
+
+To solve this problem 802.1Q Ethernet sub-interfaces, one for each supported
+guest VID. The primary vid is still untagged by the bridge and it accesses
+services running on the bridge and is re-tagged based on PVID, whereas all the
+guest traffic is untagged by the sub-interfaces, which in turn has services
+running on them. The sub-interface can then correctly re-tag the egress packet.
+
+The sub-interfaces require their own DHCP server, firewall rules and network
+configuration, which are setup accordingly by map-agent.
+
+### Default Firewall Rules
+
+The default firewall rules added will:
+* Forward guest zone traffic to wan zone
+* Reject INPUT and FORWARD traffic
+* Whitelist DHCP, DNS and ping betweens guest client and guest bridge sub-interface
+
+### Bridge Vlan Usage
+
 Individual VLAN IDs for ports are configured using *bridge-vlan* network config
 entries. A bridge-vlan section allows a configuration of how a VLAN ID should
 be appended or untagged at the bridge and each specified port.
