APAR Error Description / Circumvention

-----------------------------------------------
NAT firewall packet rules are not hiding internal network IPs
from the external network.

CORRECTION FOR APAR SE43639 :
-----------------------------
Filter Rules load for NAT with subnet settings corrected.

CIRCUMVENTION FOR APAR SE43639 :
--------------------------------
A work around to this fix is to define NAT rules with a HIDE IP
range that matches the subnet setting.  IP NAT rules for range
are not affected by this issue.
