NAT Config Problems

["Eric K. Miller" <emiller%thecreation.com@localhost>]

Hi,

I've gotten NetBSD 1.3 installed on my Amiga with two Ariadne's in it, one
connected to a static IP address on the Net, the other connected to my LAN.
They both work flawless with an httpd proxy and I can telnet in on one and
out on the other.

Now, I'm trying to get NAT to work.  My Ethernet setup:

#thecreation:/home/emiller> ifconfig le0
le0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        media: autoselect status: active
        inet 198.109.165.183 netmask 0xffffffe0 broadcast 198.109.165.191

#thecreation:/home/emiller> ifconfig le1
le1: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        media: autoselect status: active
        inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255

My ipnat.conf file:

map le0 192.168.0.1/24 -> 198.109.165.183/32 portmap tcp/udp 10000:11000
map le0 192.168.0.1/24 -> 198.109.165.183/32

I basically want everything that comes into le1 that's headed for the
Internet to be translated to come out with a return address of my static IP
address on le0.  Am I doing something wrong here?  I've switched the le0 to
le1 in the ipnat.conf file and no change.

With the ipnat.conf file set with le0 in the map statement, when I telnet
to 192.168.0.1 from my Mac (set to 192.168.0.2) I get:

#thecreation:/etc> ipnat -l
List of active MAP/Redirect filters:
map le0 192.168.0.0/24  -> 198.109.165.183/32  portmap tcp/udp 10000:11000
map le0 192.168.0.0/24  -> 198.109.165.183/32

List of active sessions:
MAP 192.168.0.1     23    <- -> 198.109.165.183 10000 [192.168.0.2 2056]
112 0 d274

This works fine, but if I telnet to anything else, it immediately drops the
connection because DNS isn't working.  I can even telnet to an IP address
and it immediately drops.

By the way, netstat -r -n returns (198.109.165.161 is a router):

Anyone know what I'm doing wrong?

Thanks!
