When do I need to configure additional IP addresses on my Barracuda Link Balancer?

  • Type: Knowledgebase
  • Date changed: 10 months ago
Solution #00004345

Scope:
All Barracuda Link Balancer models, all firmware versions.

Answer:
You may need to add Additional IP Addresses used for 1:1 NAT, or port forwarding on a static link configuration if:
  • If the built-in firewall of the Barracuda Link Balancer is disabled, only the traffic destined for the Additional IP Addresses is passed to your firewall.
  • If the built-in firewall of the Barracuda Link Balancer is enabled, the Additional IP Addresses are the external IP addresses that are eligible to be used for 1:1 NAT or port forwarding rules to direct traffic to systems on the local network.
Click Discover to populate a list of IP addresses of live systems that are on the same Class C network as this WAN interface. The Discover button is only visible if there are no entries in the Additional IP Addresses list and if the built-in firewall is disabled. Enter an IP address and click Add to add to the list of Additional IP Addresses manually.
