Layer 4 TCP and Layer 4 UDP

Layer 4 load balancing of TCP or UDP traffic. You can deploy these services in either a one-armed configuration or a two-armed configuration:

• One-Armed Using a TCP or UDP Virtual Service - Enable Direct Server Return on each of the servers. See Direct Server Return deployment.

• Two-Armed with Layer 4 Load Balancing - The default gateway for the server should be directed to the LAN IP address, the interface IP address for the Barracuda Load Balancer ADC where the server is located.
