静态NAT不行啊!natd: instance default: aliasing address not given

[mc6800]

gw# natd -redirect_address 192.168.3.2 222.16.138.1
natd: instance default: aliasing address not given

己经在/etc/rc.conf加上
ifconfig_fxp0="inet 192.168.3.1 netmask 255.255.255.0"
ifconfig_rl0="inet 222.16.138.250 netmask 255.255.255.0"
ifconfig_rl0_alias0="inet 222.16.138.1 netmask 255.255.255.0"
defaultrouter="222.16.138.254"

狂试了N次都不行，
系统是FreeBSD 6.2
内核选项
options IPFIREWALL
options IPDIVERT
options IPFIREWALL_DEFAULT_TO_ACCEPT
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=10
options IPFIREWALL_FORWARD
options DUMMYNET

整个配置文件
ifconfig_fxp0="inet 192.168.3.1 netmask 255.255.255.0"
ifconfig_rl0="inet 222.16.138.250 netmask 255.255.255.0"
ifconfig_rl0_alias0="inet 222.16.138.1 netmask 255.255.255.255"
defaultrouter="222.16.138.254"

gateway_enable="YES"
firewall_enable="YES"
firewall_type="OPEN"
natd_interface="rl0"
natd_enable="YES"

NAT是正常的（网内用户可以正常上网），就是配静态NAT不行
