Connection Table Size
The connection tracking table size configuration menu is used if you need to increase the size of your
connection tracking table (used for NAT). Since each connection must be tracked to be properly routed
back to clients, this table must be large enough to accommodate all simultaneous connections. Old
connections are dropped after a period of time.
While sufficient table entries are required, particularly since most connections create several table
entries, you want to ensure you don't try to create a table so large it uses all available memory. In fig 6
below, it would be imprudent to create a table taking more than about 15MB of memory (approx 48,000
rows). The default of 16384 rows should be sufficient for a large number of clients (depending on your
traffic mix).
