ros设置upnp ps4故障

我就是困

ps4连接ros的lan口，设置upnp，ps4连接多人房间后1分中掉线，连接类型显示nat2.ros wan口公网地址。


dhcp-server pri detail
Flags: X - disabled, I - invalid
0 name="ceshi" interface=LAN lease-time=3d address-pool=111 bootp-support=dynamic bootp-lease-time=forever authoritative=after-2sec-delay always-broadcast=yes

/ip dhcp-server network pri
# ADDRESS GATEWAY DNS-SERVER WINS-SERVER DOMAIN

ip upnp pri
enabled: yes
allow-disable-external-interface: no
show-dummy-rule: yes

防火墙规则为空

ip upnp interfaces pri
# INTERFACE TYPE FORCED-EXTERNAL-IP
0 LAN internal
1 WAN external

按照以上设置，在nat上可以看到：
2 D chain=dstnat action=dst-nat to-addresses=10.0.0.253 to-ports=9308 protocol=udp dst-address=0.0.0.0 dst-port=9308
3 D chain=dstnat action=dst-nat to-addresses=10.0.0.253 to-ports=65395 protocol=udp dst-address=0.0.0.0 dst-port=65395
4 D chain=dstnat action=dst-nat to-addresses=10.0.0.253 to-ports=9305 protocol=udp dst-address=0.0.0.0 dst-port=9305

建立了动态转发，但是匹配流量为0

只有手动设置
1   chain=dstnat action=dst-nat to-addresses=10.0.0.253 protocol=udp dst-address=114.112.124.46 in-interface=WAN
ps4登录正常，且不再掉线。

请教这是upnp有问题吗？
