<div dir="ltr"><div><div><div><div>Hi Fabian,<br><br></div>Our approach was to
deploy dual stack, so every router, server and host have an IPv6 and an
IPv4 address. So if something wants to communicate with another device
that have an IPv6 address, it will use its IPv6 address as the source.
If it wants to communicate with a device that have an IPv4 address, it
will use its IPv4 address as the source. If it wants to communicate with
a device that have both IPv6 and IPv4 addresses, it depends on the OS
what is preferred. <br><br></div>That way we do not need NAT64. We will phase out IPv4 when it is not needed anymore for internet or local communication.<br><br></div>Regards<br><br></div>John<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On 13 May 2016 at 09:35, Fabian Jr <span dir="ltr"><<a href="mailto:afabbie@hotmail.com" target="_blank">afabbie@hotmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div><div dir="ltr">Folks…<br><br>We are looking into way we can gradually deploy IPv6 in our network…<br><br>Already
we have it running and we have one Test Machine……. The challenge we are
facing is that from that machine with IPv6 and from other Machines with
IPv4 we can’t communicate in either direction..<br><br>IPv6 Machine just communicate with IPv6 only machines like wise IPv4 Machines just communicate with IPv4 machines ….<br><br>A work around is to do NAT64 between the two subnets….<br><br>It seems the hardware (Cisco 2921 router with IOS Version 15.0) can’t do NAT64……..<br><br>From
the internet it seems NAT64 runs on IOS-XE and IOS-CGSE which are
Hardware dependent……..seems that we can’t upgrade IOS Version 15.0 to
any the two which supports NAT64.<br><br>Before committing any expenses to acquire new router we want to reach out to the community for comments and advises….<br><br>Pls. review and advise.<br><br>Thank you…<br><br> <br>
