[Solved] NAT (port forwarding) broken after update from 2.0.3 to 2.1-RC0

[Klaws]

I had several port forwards configured under 2.0.3. After the update to 2.1-RC0, they are still displayed, but none of them work (connections via WAN time out). I can still access the WebGUI via WAN (I have a firewall rule to permit this in place).

I am not using NAT reflection.

Seems that the error mentioned in this post:

caused the NAT failure as a side effect. I disabled the floating rule mentioned in the other post and NAT worked again.
