Re: Destination unreachable, USG20 confused
Its definitely the USG. As the log shows, the return packet is rejected by the USG.
Note, the packet is rejected, not simply dropped. All my firewall rules drop. Thus, the rejection is not from a rule.
Seems like there is a session because otherwise it should just be dropped. But then the NAT fails as if there is no session.
I really think this is a bug.
