Email Security Gateway models 300 and higher using Per User Quarantine, all firmware versions.
The action links (Deliver, Whitelist, and Delete) within the Spam Quarantine Summary Report will reference the Barracuda's IP address. In a NAT environment where the Barracuda is on the LAN, the summaries will not work from outside of the network unless the Quarantine Host field has been filled in with either a public hostname or IP with the appropriate port forwarding or NAT rules in place. To correct this problem, follow these steps:
- Navigate to the Basic > Quarantine page of the Email Security Gateway's web interface.
- Enter a hostname or publicly accessible IP address into the Quarantine Host field that users can use to communicate with the Barracuda.
When using an external IP or hostname as the Quarantine Host in situations where the Barracuda is on a LAN, you will need to ensure that all port 8000 inbound and outbound traffic on that IP or hostname goes directly to the Email Security Gateway. For security reasons, you may also want to explicitly specify which IPs are allowed to log into the Email Security Gateway as administrator (to do this, see Solution #00001547).
