I would like to use ipfilter to achieve NAT (Network = Address

Translation) and packets forwarding. I find the = ipfilter=20 tools,

such as ipnat, ipf, ipftest and so on have been = involved=20 into

FreeBSD 3.0. But when I use ipnat to fulfill NAT and = packets

forwarding. The system hints me with a error=20 information:

So, what can I do to solve the=20 problem?
