>Description:
After being used as IP NAT gateway for about 50 hosts for two days my
system had a lot of dead IP NAT connection in its table (as shown by
"ipnat -l"). When I tried to flush them with "ipnat -F" the system
freezed immediatley and I had to hard reset it. The IP NAT configuration
looked like this:

map de0 192.168.1.0/24 -> 193.175.205.211/32

>How-To-Repeat:
Use a host as IP NAT gateway for a while and enter "ipnat -F".

>Fix:
Sorry, no idea.
