Yes, I just try step by step. More over I don't have second nic (and no chance no cache another one), so that will be difficult :( > As I said, I have virtually the same IPv6 setup as Guy has, > but I don't have the problem on my C3000. > Thanks again, Joel _______________________________________________ parisc-linux mailing list parisc-linux@lists.parisc-linux.org http://lists.parisc-linux.org/mailman/listinfo/parisc-linux
