Explanation
What is the default size of NAT table fwx_alloc? The default size of NAT table fwx_alloc is 25000. This table stores the connections that require NAT translation by the Security Gateway. The size of this table can be changed by using the command fw ctl set int fwx_alloc <value>, where <value> is the desired number of connections. The maximum value is 65535. To make this change permanent, you need to add this command to the file $FWDIR/conf/fwaffinity.conf on the Security Gateway. References: [R81 Performance Tuning Administration Guide], page 126.
