@Ronmaupin @Zac67 Hi Gentleman, could you please check my post "Assign a new public and static IP to a router behind my main route" it's on hold, I edit the post to comply the rules of the group. I appreciate
The problem is the question that you are asking of us:
In IPv6 I know that IPv6 Tunnel Brokers exists and works well but is there something for IPv4 ?
In any case, you got an answer and accepted it. A tunnel broker is really just a VPN provider (IPv6 over IPv4), and there are many of those for IPv4 (IPv4 over IPv4), but we cannot recommend one.
