Receive "ERR_CONNECTION_REFUSED" when using ipv6 address to access port 8081 from external devices browser.(using brackets around ipv6 address) ipv4 address with port 8081 responds. Are there configuration parameters to change on 5268AC modem? Checked addresses used with test-ipv6.com
I switched pack to ipv6 on my local LAN. I undated my firewall rules to permit input and output to the ipv6 address and video port on my linux processor. The solution is working with ipv6 addresses. The key was finding the correct ipv6 address for my linux processor and forgetting what I knew about ipv4 internal network addresses.
