求助，ss_tunnel配置dns转发，tcp可用，udp不可用

[laole918]

/etc/config/shadowsocks-libev配置如下，OpenWrt IP是192.168.1.159

config ss_tunnel
        option disabled 0
        option server 'sss0'
        option local_address '0.0.0.0'
        option local_port '8053'
        option tunnel_address '8.8.8.8:53'
        option mode 'tcp_and_udp'//这里使用udp_only也无法启动udp服务
        option timeout '60'

在Mac命令行测试如下，Mac跟OpenWrt在同一个网络环境下。

➜  ~ nslookup -port=8053 google.com 192.168.1.159//udp测试
;; connection timed out; no servers could be reached

➜  ~ nslookup -vc -port=8053 google.com 192.168.1.159//tcp测试
Server:		192.168.1.159
Address:	192.168.1.159#8053

Non-authoritative answer:
Name:	google.com
Address: 172.217.160.110

OpenWrt固件版本如下两个测试均有问题
openwrt-22.03.5-x86-64-generic-ext4-combined-efi.img.gz
openwrt-23.05.2-x86-64-generic-ext4-combined-efi.img.gz
