Test the network on the computer

Install brook CLI on the computer

At this time, re-plug the computer's network cable and automatically obtain the IP. You should be able to obtain GUA, and DNS should also be GUA

brook dnsclient -d http3.ooo -t A -s 192.168.2.1:53
brook dnsclient -d http3.ooo -t AAAA -s 192.168.2.1:53
brook dnsclient -d http3.ooo -t A -s [xxx]:53
brook dnsclient -d http3.ooo -t AAAA -s [xxx]:53

xxx is the IPv6 GUA DNS obtained by your computer

brook echoclient -s 137.184.237.95:7777
brook echoclient -s [2604:a880:4:1d0::4cf:b000]:7777

Test the network in OpenWrt

Download brook CLI, rename it to brook and copy it to OpenWrt

brook dnsclient -d http3.ooo -t A -s 127.0.0.1:53
brook dnsclient -d http3.ooo -t AAAA -s 127.0.0.1:53
brook dnsclient -d http3.ooo -t A -s [::1]:53
brook dnsclient -d http3.ooo -t AAAA -s [::1]:53

brook echoclient -s 137.184.237.95:7777
brook echoclient -s [2604:a880:4:1d0::4cf:b000]:7777

You can also test your Brook Server

brook testbrook --link 'brook://...'

If necessary, upgrade OpenWrt

As of this article, the latest version is 24.10.0, download openwrt-24.10.0-mediatek-filogic-openwrt_one-squashfs-sysupgrade.itb
Upgrade via OpenWrt web
- System - Backup / Flash Firmware - Flash images

Install dependencies

opkg update
opkg install ca-bundle kmod-nf-socket kmod-nft-socket kmod-nf-tproxy kmod-nft-tproxy procps-ng-ps

Run brook.openwrt

Download brook.openwrt CLI renamed to brook.openwrt and copied to OpenWrt

brook.openwrt --link 'brook://...'

Test the network on your computer

Take a look at the two DNSs assigned to your computer, one IPv4, one IPv6

brook dnsclient -d http3.ooo -t A -s 192.168.2.1:53
brook dnsclient -d http3.ooo -t AAAA -s 192.168.2.1:53
brook dnsclient -d http3.ooo -t A -s [xxx]:53
brook dnsclient -d http3.ooo -t AAAA -s [xxx]:53

xxx is the IPv6 GUA obtained by your computer DNS

Test IPv4 and IPv6, TCP and UDP, of course your Brook Server should support dual stack

brook echoclient -s 137.184.237.95:7777
brook echoclient -s [2604:a880:4:1d0::4cf:b000]:7777
