What make and model router are you using?
What specific ports do you need forwarded to the server?
I see the Server's IPv4 and IPv6 IP addresses. You have IPv6 service - correct?
However, I am not sure I understand (full disclosure) the script you have provided.
It appears to me that all the ports from 80 - 443 (inclusive) are being forwarded with respect to IPv6. Not with respect to IPv4.
Please add more information. Someone else may be able to spot what I am missing here. Okay with me.
Thanks.
