What About IPv6? How Long Until Widespread Deployment?

Posted by Cliff on from the don't-hold-your-breath dept.

Christopher Blood asks: "Over at the register, they talk about the EU adopting IPv6. So what about the USA? When do we get it? IPv6 would solve some and DOS problems and we will need the extra address space. What's the holdup?" While IPv6 may be the cure for all of our IPv4 ills, upgrading the whole internet to the new technology isn't going to happen over night. What has been done to prepare for the jump, and what still needs to happen before it can become a reality?

    OK, I am about to say something that will make many of you who are knowledgable about IPV6 cringe, so take a deep breath and get over it now.

    When IPV6 is deployed, how do I prevent the machines on the inside of my firewall from being routable?

    Right now, my personal computer is on the inside of a NAT firewall. There is no way you can route a packet to it - go ahead, try to telnet to 10.200.120.4, I dare you.

    Now, I know there are those who say NAT CONSIDERED HARMFUL, and I agree in the general case it does break the essential peer to peer nature of TCP/IP.

    But what if I want to break it?

    How well tested are the Linux kernel modules for firewalling IPv6? Can I still protect my internal machines from the slings and arrows of outragous 5|<197 |<!66!3Z?
