Chapter 2: Installing the Barracuda Link Balancer 9
• The Barracuda Link Balancer LAN IP address can be any internal or public address that is
reachable through your existing firewall from the LAN. You may allocate an external IP address
for it, or choose a non-routable IP address. If the latter, it should be on a different subnet than the
LAN devices already on the network. Remember that if the firewall does not recognize an
address as being on the local network it will pass it to the Barracuda Link Balancer.
