"...circumvent normal socket functions..." My understanding is that IPV6 has it's own tools, including IP6Tables. Though I seem to have gotten IPTables to accept IPV6 as an open/closed port. I'm doing the research on it personally. Right now I'm basically dual stack (IPV4/IPV6) and my router is bearing the brunt of being the firewall and gateway. NAT from what I learned this weekend some sites, mostly banking are still requiring. Boiled down NAT is block everything coming in and watch you let out. Some sites record me as running IPV4 and others pick up my IPV6 allocation. We shall see how this all comes out, but I'm liking it overall. There are some sites out in the web, streams, tv shows, etc that only broadcast on the IPV6 side. gk
