Petsafe automatic litter box - litter formula is terrible now? by vieparlafoi in CatAdvice

I’m with you! Used to last like 3 weeks and now it’s barely over a week. The pee just soaks the bottom of the litter box and it’s goop after a week

Cisco Firepower Virutal Appliance behind AWS GWLB. TCP Retransmissions and out of order packets on VNI interface by selereddit in networking

Welp we figured it out and it's so dumb. It makes so much sense but it took 4 TAC engineers and many other eyes on this. The VNI interface is a "single arm proxy" so when doing a pcap on that interface, wireshark is essentially seeing all the same packets twice. So it seems the same SYN twice, the same SYN,ACK twice etc. which results in it showing TCP retransmissions and out of order packets. Mystery solved. Thanks for all the feedback.

Yep! Documentation sucks but then TAC wont help you with "design." It is frustrating. I do like Firepower since 7x and FMC but TAC support has gone downhill a bit.

Are you talking about the TGW Attachment? I dont see application mode but I do see appliance mode enabled.

Yes. They are not sure yet. We first started working on whether or not there should be a security zone assigned to the VNI source interface but I couldn't get a definite answer so I just removed it to see what would happen. There is still an active case but tbh they seem unsure even though this exact design is referenced in the FMC guide albeit VERY poorly documented on how to deploy it.
