After install the image in the VMM, need to update the network config

1. gateway
2. dns

``` config interface 'lan'

option type 'bridge'
option ifname 'eth0'
option proto 'static'
option ipaddr '192.168.1.18'
option netmask '255.255.255.0'
option ip6assign '60'
option multipath 'on'
option gateway '192.168.1.1'
list dns '8.8.8.8'

```

https://openwrt.org/docs/guide-user/luci/luci.essentials ``` opkg update opkg install luci ```

``` opkg install curl unzip wget-ssl ipset

```

Download the v2ray from

1. https://github.com/v2ray/v2ray-core/releases

I use my VPS to download it first

wget https://ef.pjq.me/download/openwrt/v2ray-linux-64.zip
unzip v2ray-linux-64.zip -d v2ray

``` opkg install kmod-tcp-bbr insmod kmod-tcp-bbr lsmod|grep bbr ```

vim /etc/sysctl.conf

And add the following:

net.core.default_qdisc=fq_codel
net.ipv4.tcp_congestion_control=bbr

Then reload the setting

sysctl -p

``` lsmod|grep bbr tcp_bbr 16384 35 ```
