evaluating Automap port usage
One drawback of using Automap is source TCP port exhaustion. Is there a convenient way to view the "high water mark" for Automap source port usage for a specific self IP address?
The rule of thumb is 60k concurrent connections per SNAT pool member. Just keep an eye on your connection counts and always build your configuration so that the box tips over before the max of your configuration is reached.
Keep in mind that multiple Virtual Servers using SNAT automap means you have to aggregate your connection counts across the applications. There are easy ways to see these connection counts via the TMUI (in statistics) or from the command line.
IP's tend to come cheaply, when in doubt build larger than needed.
