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.
