Hello,

Depending on platform of PIX, there can be different upperbound limit for # of XLATE entries that the hardware can support.

For a PIX 515E 400 NAT entries should not be much of a problem and 20% memory usage is also quite normal at high usage I have seen memor rise upto 90 % and above. Normal memeory usage for your firewall is around 70-80 %. And usually firewalls can support around 10s of 10000s of NAT/ACL entries. There may have been stress testing done for getting the exact number , but I guess there is no document to testify the figures (datasheets may help)..

Thanks,

Vijaya
