OpenWRT allow IPv6 access LAN host from the Internet

cn flag

I'm new to IPv6 and trying to figure out how to properly configure my router so that I can access a web server through OpenWRT from the Internet.

With IPv4, I use port forwarding. For example, forward port 8080 of the WAN interface to 192.168.1.123:8080. This way I can access the webserver using my public IPv4 address at port 8080.

With my rudimentary understanding of IPv6, I assume I can have OpenWRT assign a global unicast IPv6 address to my webserver, and configure the firewall to allow connections from the internet to that IPv6 address, without using port forwarding.

My ISP assigns a /64 prefix, e.g. 2000:aaaa::1234/64. I want to configure OpenWRT to assign a static IPv6 address to the web server, something like 2000:aaaa::1234:5678/128. Then configure the firewall so that I can access the web server using [2000:aaaa::1234:5678]:8080.

Again, my IPv6 knowledge is limited. Please correct any wrong statements above and help me understand how to do this correctly.

For your business network, the `/64` is your transit network, and the ISP should delegate a prefix like `/48` for use in your network, the you just route.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
