Hello All, I have 2 sites connected to different Internet ISPs. Site-1 is with IPv4 IP address, Site-2 is with IPv6 IP address on WAN interface and IPV4 (Private IP address range) on LAN side. 

 

I am asked to configure GRE Tunnel between these 2 sites. Can i establish GRE tunnel betwen IPv4 and IPv6?

 

Thanks/Sairam

You would need nat64 for that, but GRE is not supported by NAT64. Your best option would be to deploy IPv6 at both sites.
