Understanding ServerIron FWLB
Firewall Load Balancing (FWLB) allows the ServerIron ADX to balance traffic on multiple firewalls.
The ServerIron ADX supports the following IPv4 FWLB topologies: Basic FWLB, High Availability (HA)
FWLB, and Multizone FWLB.
The ServerIron ADX supports the following IPv4 topologies: FWLB + NAT, FWLB + SYN Proxy, FWLB +
L4 SLB.
The ServerIron ADX supports the following IPv6 FWLB topologies: Basic FWLB and High Availability
(HA) FWLB.
IPv6 FWLB is only available on the Router Image.
You can configure FWLB for IPv6 topologies; however, the command line interface (CLI) does not
accept IPv6 addresses for all commands.
Table 1 provides a list of affected commands that enable
you to configure IPv6 FWLB as well as the show commands.
