Question about portforwarding

Hello,

I am currently trying to port forward from a Linux Virtual Machine, it has a different ipv4 and ipv6, which is normal. However, the problem comes when I go to 10.0.0.1 and I try to port forward, but I can't because I am not able to edit the ipv6 address, it is just grayed out.

Is there any way I can edit the ipv6 address while in the port forward process?

Thank you,
