All NAT inbound packs get blocked after update.

[wangjiaxiang]

Hi, I just updated my opn from 18.x to 19.7. But after restarting the server , I lost NAT forever.

I checked firewall logs and found messages about inbound NAT packs blocked.

Finally, I located the auto-generated floating rules that caused this issue, with description "block all targetting port 0", which block all ipv4+6 tcp/udp packs. (screenshot attachment below).

I believe they are the reason for my issue. But I cannot delete them.

I need your help!

Thank you!
