Is it possible to have MOL networking under Debian?

[Renaud Dreyer <rdreyer@math.berkeley.edu>]

I've been trying to get MOL networking up and running with the
ethertap method in the MOL FAQ (http://www.turbolinux.com/~brad/mol/#ppp) 
without any success. 

Since the method described in the FAQ comes from someone probably 
running LinuxPPC, I'm wondering if there's anything in that method 
specific to LinuxPPC, and if there's anything I can do to make it 
work under Debian. Can ayone see something "un-Debian" in what I 
describe below?

I'm running Debian on a PowerMac 7300 with a Cable Modem and a static
IP address. I'm running the latest MOL (0.9.41), from an alienated
RPM. I have a kernel (2.2.1 5pre11 from Paul's tree) with IP
masquerading and ethertap compiled in. I'm completely stumped and
would like to know how other people go this working! 

I followed the FAQ to the letter and nothing is working. This is what
I did:

*Created ethertap device:

cd /dev; /bin/mknod tap0 c 36 16

*Configured it:

insmod ethertap
ifconfig tap0 192.168.0.1 netmask 255.255.255.0 up arp
route add -host 192.168.0.1 tap0
echo "1" > /proc/sys/net/ipv4/conf/tap0/proxy_arp
arp -s 192.168.0.2 FE:FD:00:00:00:00 pub

*Got IP masquerading going:

echo "1" >/proc/sys/net/ipv4/ip_forward
ipchains -M -S 7200 10 160
ipchains -P forward DENY
ipchains -A forward -s 192.168.0.0/24 -j MASQ

*Set up networking in /etc/molrc:

disable_osi_enet:       no
enet_interface: tap0

*Entered the following in Mac OS' TCP/IP control panel:

         Connect via     : Ethernet
         Configure       : Manually
         IP address      : 192.168.0.2
         Subnet mask     : 255.255.255.0
         Router address  : 192.168.0.1
         Name server addr: __ISP's_name_server_addr__ (same as under Linux)


The problem is that I can't even ping the linux side (192.168.0.1)
from the Mac OS side (192.168.0.2) or vice-versa, so I know it's not
an IP masquerading problem, since the "machines" on the internal
network should at least be able to see each other.

I have the following modules loaded:

Module                  Size  Used by
ethertap                3216   1
sheep_net               4032   0
mol                    31592   0

This is what ifconfig gives me:

          inet addr:24.6.255.22  Bcast:24.6.255.255  Mask:255.255.255.0

... and netstat -rn:
