安装所需的软件包。 指定 VPN 服务器配置参数。
# 安装相关的软件包 opkg update opkg install wireguard-tools # 设置连接参数 WG_IF="vpn" WG_PORT="51820" WG_ADDR="192.168.9.1/24" WG_ADDR6="fd00:9::1/64"
在服务器与客户端之间生成并交换密钥
# 生成密钥 umask go= wg genkey | tee wgserver.key | wg pubkey > wgserver.pub wg genkey | tee wgclient.key | wg pubkey > wgclient.pub wg genpsk > wgclient.psk # 私钥 VPN_KEY="$(cat wgserver.key)" # 预共享密钥 VPN_PSK="$(cat wgclient.psk)" # 公钥 VPN_PUB="$(cat wgclient.pub)"
将 VPN 网络视为私有网络。 将 VPN 接口分配到 LAN 区域,以尽量减少防火墙设置。 允许从 WAN 区域访问 VPN 服务器。
# 设置防火墙 uci rename firewall.@zone[0]="lan" uci rename firewall.@zone[1]="wan" uci del_list firewall.lan.network="${VPN_IF}" uci add_list firewall.lan.network="${VPN_IF}" uci -q delete firewall.wg uci set firewall.wg="rule" uci set firewall.wg.name="Allow-WireGuard" uci set firewall.wg.src="wan" uci set firewall.wg.dest_port="${VPN_PORT}" uci set firewall.wg.proto="udp" uci set firewall.wg.target="ACCEPT" uci commit firewall service firewall restart
配置 VPN 接口和节点。
# 设置网络 uci -q delete network.${VPN_IF} uci set network.${VPN_IF}="interface" uci set network.${VPN_IF}.proto="wireguard" uci set network.${VPN_IF}.private_key="${VPN_KEY}" uci set network.${VPN_IF}.listen_port="${VPN_PORT}" uci add_list network.${VPN_IF}.addresses="${VPN_ADDR}" uci add_list network.${VPN_IF}.addresses="${VPN_ADDR6}" # 添加 VPN 节点 uci -q delete network.wgclient uci set network.wgclient="wireguard_${VPN_IF}" uci set network.wgclient.public_key="${VPN_PUB}" uci set network.wgclient.preshared_key="${VPN_PSK}" uci add_list network.wgclient.allowed_ips="${VPN_ADDR%.*}.2/32" uci add_list network.wgclient.allowed_ips="${VPN_ADDR6%:*}:2/128" uci commit network /etc/init.d/network restart
建立 VPN 连接。 使用 traceroute 和 traceroute6 命令确认流量是否通过 VPN 网关。
traceroute openwrt.org traceroute6 openwrt.org
检查客户端IP地址:
请确保客户端没有DNS泄露(DNS leak)发生:
# 重启服务 service log restart; service network restart; sleep 10 # Log and status logread -e vpn; netstat -l -n -p | grep -e "^udp\s.*\s-$" # Runtime configuration pgrep -f -a wg; wg show; wg showconf vpn ip address show; ip route show table all ip rule show; ip -6 rule show; nft list ruleset # Persistent configuration uci show network; uci show firewall; crontab -l
