What version of WebOS did you use for this? On SDK version 1.4.1 or 1.4.5, both of which use Linux kernel version 2.6.26, when I attempt to list what's in the "nat" table I get the error:
# iptables -t nat -L -n iptables v1.4.2: can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.
Other attempts to use iptables with "-t nat" get similar results. I haven't followed the instructions from the beginning, but I don't see anywhere in there that it installs the required kernel module. At the moment I don't know where to get the required kernel module.
(Added later) The above problem apparently happens only with the Palm SDK emulator. A real Palm Pre seems to have NAT built in. The one I'm testing against runs Kernel version 2.6.24, not 2.6.26, and "iptables -L -n -v -t nat" works fine.
5/5/2011 - pixxels I'm attempting this now on my original palm pre. Is root access still required? Or is there a preware app/package that will do this all for me now. :)
Delta's I observed doing running process
