APPENDIX A

Firebox SSL VPN Gateway 
Monitoring and Troubleshooting

The following topics describe how to use Firebox SSL VPN Gateway logs and troubleshoot issues:

• Viewing and Downloading System Message Logs
• Enabling and Viewing SNMP Logs
• Viewing System Statistics
• Monitoring Firebox SSL VPN Gateway Operations
• Recovering from a Failure of the Firebox SSL VPN Gateway
• Troubleshooting

Viewing and Downloading System Message Logs

There are two types of logging for the Firebox SSL VPN Gateway. All of the logs are stored locally and can 
be viewed from either the Administration Tool or the Administration Portal. Optionally, this same infor-
mation can be sent to a syslog server.
System message logs contain information that can help Firebox SSL VPN Gateway support personnel 
assist with troubleshooting. By reviewing the information provided, you can track unusual changes that 
can affect the stability and performance of the Firebox SSL VPN Gateway.
System message logs are archived on the Firebox SSL VPN Gateway for 30 days. The oldest log is then 
replaced with the current log.
You can download one or all logs at any time. You can also have system messages forwarded to your sys-
log server, as described in “Forwarding System Messages to a Syslog Server” on page 138.

  

Note

If you need to view the system log and the Firebox SSL VPN Gateway is offline, go to the Administration 
Portal and click the 

Logging

 tab.

To view and filter the system log

1

In the Administration Tool, click the 

VPN Gateway Cluster 

tab.

2

Open the tab for the Firebox SSL VPN Gateway.
