I'm trying to get NAT up and running on 1.5.  My setup is a two 
Ethernet card setup with one connected to my DSL modem which uses 
PPPoE and the other connecting to my network.  I've set it up 
according to all the info I could find on it and can't determine 
what's going wrong.  I can ping the machine but I can't get network 
traffic back. My config files:

ipnat.conf
map ppp0 192.168.1.0/24 -> 0/32 proxy port ftp/tcp
map ppp0 192.168.1.0/24 -> 0/32 portmap tcp/udp 1000:65535
map ppp0 192.168.1.0/24 -> 0/32

ifconfig.sn0 (connected to DSL modem)
inet 0.0.0.0 netmask 255.255.255.0

ifconfig.ae0 (connected to network)
inet 192.168.1.0 netmask 255.255.255.0

rc.conf
<snip>
ipfilter=YES
ipnat =YES
auto_ifconfig=YES
<snip>
portmap =YES

Anything else I need to do on the above?

The results from netstat -i show that the packets from the requesting 
machine are going out over ppp0 but not coming back in.  So it looks 
like the internal packets are getting out to the internet, just not 
coming back in.  What gives with this?
