hi, 
my NAT doesn't work:(((
could anyone tell me why?

i try to ping 194.204.159.1 from 192.168.1.2 and it doesn't work, 
but ping from 192.168.1.2 to 192.168.1.1 works.
so what's wrong with my ipnat configuraion? :


ifconfig  ne2 & ppp0 :

ne2: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	address: 00:c0:26:b6:23:ae
	media: Ethernet autoselect (10baseT)
	inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
	inet6 fe80::2c0:26ff:feb6:23ae%ne2 prefixlen 64 scopeid 0x1

ppp0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1656
	inet 217.96.203.150 -> 217.96.203.150 netmask 0xffffff00
	inet6 fe80::2c0:26ff:feb6:23ae%ppp0 -> :: prefixlen 64 scopeid 0x3



cat /etc/ipf.rules:

pass in from any to any
pass out from any to any



I run ipnat :

ipf -Fa -f /etc/ipf.rules -E
ipnat -CF -f /etc/ipnat.rules


then ipnat -l:

List of active MAP/Redirect filters:
map ppp0 192.168.1.2/32  -> 217.96.203.150/32  portmap tcp/udp 40000:60000
map ppp0 192.168.1.2/32  -> 217.96.203.150/32 
map ppp0 192.168.1.2/32  -> 217.96.203.150/32  proxy port ftp ftp/tcp



HELP ME PLEASE!!
