Claim 1:
2. The tangible, non-transitory, computer-readable medium of claim 1, wherein the computer-readable instructions comprise a routing table generated by:
determining a number of the plurality of stateful firewall instances, zones, or both available to the virtual network;
dividing the routable space protected by the number of the plurality of stateful firewall instances into a number of blocks equaling the number of the plurality of stateful firewall instances, zones, or both;
creating an assignment for each division of the routable space to a particular one of the stateful firewall instances,
based upon the assignment, generating the routing table, where the cross-zone traffic is routed symmetrically and the external network traffic is routed to a particular one of the stateful firewall instances assigned to a particular division of the routable space associated with a source of the external network traffic.
