Hi,

I am trying to set up IP Masquerading on a NetBSD box with IPNAT and cant 
seem to get it to work!!

Here are my settings. Two NICs, one wired to the net through cable 
modem(rtk0) and a the second NIC configured for my local network along with 
my client PCs

here are my relavent configuration files

/etc/rc.conf
ipfilter=YES
ipnat=YES
host="cr281793-b.wlfdle1.on.wave.home.com"
auto_ifconfig=NO
net_interfaces="rtk0 ne2"
ifconfig_rtk0="inet 24.42.160.18 netmask 255.255.255.128"
ifconfig_ne2="inet 192.168.1.1 netmask 255.255.255.0"
defaultroute="24.42.160.1"  # Cable Connection Gateway

/etc/ipnat.conf
map rtk0 192.168.1.1/24 -> 0/32 proxy port ftp ftp/tcp
map rtk0 192.168.1.1/24 -> 0/32 portmap tcp/udp 40000:60000
map rtk0 192.168.1.1/24 -> 0/32

/etc/ipf.conf
pass in from any to any
pass out from any to any

/etc/rc.local
sysctl -w net.inet.ip.forwarding=1


The NICs seemed configured correctly I can ping clients on the local network 
and can access the internet from rtk0.....

#ifconfig rtk0
rtk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        address: 00:40:f4:19:69:02
        media: Ethernet autoselect (none)
        status: active
        inet 24.42.160.18 netmask 0xffffff80 broadcast 24.42.160.127
        inet6 fe80::240:f4ff:fe19:6902%rtk0 prefixlen 64 scopeid 0x1


#ifconfig ne2
ne2: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        address: 00:60:67:3d:25:a8
        media: Ethernet autoselect (10baseT)
        inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
        inet6 fe80::260:67ff:fe3d:25a8%ne2 prefixlen 64 scopeid 0x2

#sysctl net.inet.ip.forwarding
net.inet.ip.forwarding = 1

my client machines (win 2000 server + linux) are configured 192.168.1.2/3 
with a default gateway of 192.168.1.1(BSD box) (do I have to specify DNS 
servers for my clients)

.....anyways all this jargon and still now show!!!!!!....

...I dont know if this is all I need?....any help would be greatly 
appreciated!!

it seemed alot easier on Linux with ipchains :)

thanks in advance!

peace
