[Voyage-linux] conntrack - Operation failed: invalid parameters

[Punky Tse]

Hi Peter,

So, does voyage-0.3.1 with the 2.6.17-486-voyage, does conntrack work?

And the most obvious thing is to diff the kernel config of vanilla 
2.6.16 and 2.6.20-486-voyage to see what are their difference.

If you may know, the new xt_* tables (layer 3 independent connection 
tracking - CONFIG_NF_CONNTRACK_SUPPORT) will replace the original layer 
3 dependent connection tracking - CONFIG_IP_NF_CONNTRACK_SUPPORT.

In 2.6.20, I changed the kernel to adopt the new one (i.e. layer 3 
independent).  May be this is related.
