I found out that the zaurus kernel is not configured to support netfilter/iptables, so to get these things to work I reconfigured and recompiled the kernel to support them. The only changes I made (during menuconfig) were enabling iptables/netfilter. I installed the new kernel and everything went fine. There were no problems however after a couple hours my Zaurus started locking up and the wireless connection was always giving me the signal level is low message. I know it isn't low because my router is about 2 feet away from me. This same thing happened to my friend who installed the new kernel as well. Any ideas on why this is happening? Thanks for your help.
