This definitely belongs in the FAQ list.

In A/UX 2.0.1 "ipforwarding" was turned off due to a comment in some RFC
that basically states that a host should not abitrarily become a
gateway.

You can turn ipforwarding back on by issuing the following in adb:

# adb -w /unix
a.out file = /unix (COFF format)
cannot open core
ready
ipforwarding?D
ipforwarding:   0
ipforwarding?W 1
ipforwarding:   0x0             =       0x1
$w
$q
#

Then reboot your Mac so that the change will take effect.  You might
also want to make the same change to /etc/install.d/boot.d/bnet_dr in
case you build a new kernel via newconfig at some later date.
