[preface] because the Chinese materials of OPNsense are really too little, and 51CTO has also been registered (registered in 2010) and has not been used for a long time, in this case, we will specifically write some OPNsense experiences in 51CTO.

As an ordinary PPPOE user of Guangdong Telecom, I see that the big people in the group are talking about IPV6. Guangdong supports native IPV6. So I came up with the idea of changing my outdated router with OPNsense, so I got it together. Due to the lack of information, it belongs to the blind to cross the river, and it took a long time to find out how to set it up.

Major premise: optical cat supports IPV6 access, otherwise it will be blind if the device does not support it. As for how to get into the light of the cat, how to modify it, search by yourself.

Follow the steps directly above the picture.

WAN port setting DHCPV6

Check to request only one IPv6 prefix and request IPv6 prefix / information through the IPv4 connection link. Save after setting.

Switch to LAN port, and select the last one for IPv6 configuration type: trace API

Drop down to the bottom, set tracking IPv6 information, and select the WAN that has just been configured for the IPv6 API.

The setting is very simple, just WAN and LAN settings, as for DNS will be automatically issued, do not need to set manually. Let's take a look at the situation on the PC side and get the IP again:

Visit the IPv6 website of Shanghai Jiaotong University to test: http://ipv6.sjtu.edu.cn/, when you are IPv6, it will display a smiley face and IPv6 address; if not, it will not show smiley face and prompt to use the IPv4 address
