After reading the manuals, forums and mailing lists...I still haven't
found what is wrong with my IPNAT configuration. Hopefully...somebody
will know what I have missed.

Objective: set up a gateway machine to share a single internet connection
Gateway: NetBSD 3.0 i386
Clients: Linux, Win

(1) Gateway settings

NIC 1 - rtk1 - connected to ISP via DHCP
NIC 2 - rtk0 - connected to internal network via switch

/etc/ifconfig.xxN
rtk1: !dhclient $int
rtk0: inet 10.0.0.1 netmask 0xffffff00

ifconfig output
rtk1: inet 213.143.79.9 netmask 0xffffff00 broadcast 213.143.79.255
rtk0: inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255

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

/etc/ipnat.conf
map rtk1 10.0.0.0/24 -> 213.143.79.9/32 proxy port ftp ftp/tcp
map rtk1 10.0.0.0/24 -> 213.143.79.9/32 portmap tcp/udp 40000:60000
map rtk1 10.0.0.0/24 -> 213.143.79.9/32

/etc/sysctl.conf
net.inet.ip.forwarding=3D1

/etc/rc.conf
ipfilter=3DYES
ipnat=3DYES

(2) Client settings

IP: 10.0.0.2
Gateway: 10.0.0.1

Of course, gateway can access the internet, and ping gateway < - >
client works OK, yet internet is still not available on client
machine.

What did I miss?

Many thanx in advance, Vojko.
