- Router4, for fine control of routing between your Virtual Networks
- NAT4 to enable private Virtual Networks to reach the Internet
- HAProxy Load Balancer, a robust layer4 (TCP) reverse-proxy/load-balancing solution
- Keepalive LVS Load Balancer, so called layer4 switching, a high-performance load-balancing solution
