Disregard that last post. ipfilter was updated to the current version 5
in RELEASE 10.0 and I think also for 9.3. Been using ipfilter since
RELEASE 4.0 without any problems. Its rock hard and easy to use.
map = The keyword map starts the rule.
em0 = The interface name of the interface facing the public Internet.
192.168.7.234/32 = The IP address range of the private LAN.
-> = Mandatory arrow symbol.
0.32 = The IP address/netmask assigned by your ISP.
The special alias keyword 0.32 tells ipnat to get the current
public
IP address of the interface specified on this statement and
substitute it for the 0.32 keyword.
