Comments
Real-IP
•
The trusted (eth0) and untrusted (eth1) interfaces of the CAS must be on
different subnets.
•
Add static routes on the L3 switch or router to route traffic for the managed
subnets to the trusted interface of the respective CASs.
•
If using DHCP relay, make sure the DHCP server has a route back to the
managed subnets.
NAT (testing
only)
Note: NAT is not supported for production deployments
