Hi all,
I have an IPv6 network that is working, I am running dual stack on my routers, and my computer it work fine. What I want to do is to just put an IPV6 address on my computer and with that single ipv6 go out to the internet and access both IPV6 and IPv4 address ( I don’t want to run dual stack on my computer just on my routers and switches)??????
Is their a way that I can configure my router so that when my computer running only ipv6 wants to reach a ipv4 address the router can automatically translate my ipv6 address and connect me to an ipv4 address???.
Any information or any other suggestion how to accomplish this will be highly appreciated, this is the configuration I am using at the moment on my router,
Thanks,
Danny

The internet is predominantly IPv4 at the moment so you need to translate your IPv6 to IPv4 with NAT.
Please refer to the documentation:
