I disagree, it’s probably Stateless. That can mess with connections.
JA

I’m surprised this is happening. Shouldn't it just drop the packets silently?
MA

No way, it has to be Internal. That’s a common mistake!
PE

I think it could also be Drop. That would cause RST packets too.
AV

Definitely sounds like the virtual server Type is set to Reject.

I'm leaning towards the Reject option too, but I wonder if the Stateless setting could also lead to unexpected behavior.

I practiced a similar question where the virtual server was set to Internal, and it caused connection problems, but I don't think it would send a RST.

I think the Drop option might also cause issues, but I can't recall if it sends a RST or just drops packets silently.

I remember studying that a virtual server set to Reject would definitely send a TCP RST, but I'm not sure if that's the only reason.

Hmm, Stateless is an interesting one. I wonder if that could be the reason for the TCP RST packet. I'll make sure to read through the descriptions carefully before deciding.

I think the key here is understanding how the different virtual server types handle incoming connections. If it's set to Internal, that might also cause the RST packet, so I'll consider that option too.
HO
Howard 1 year ago
Wait, I'm a bit confused. Wouldn't the virtual server type being set to Drop also result in a TCP RST packet? I'll need to double-check that.
DA

Okay, let's see. If the virtual server type is set to Reject, that would make sense for the TCP RST packet. I'll mark that one down as a possibility.

Sol 1 year ago
Hmm, this one seems tricky. I'll need to think through the different virtual server types and how they might impact the connection behavior.

Hmm, I'd say B is the way to go. Unless you want your users to feel like they're trapped in a virtual server limbo, you don't want to use Drop or Stateless.

Actually, setting the virtual server Type to Internal may also cause users to receive TCP RST packets.

Definitely B. I've seen this issue before, and the docs clearly state that Reject mode sends a TCP RST. Gotta love those helpful error messages.

Yes, Reject mode is likely causing the users to receive the TCP RST packet.

It's important to check the configuration to make sure it's not set to Reject.

I thought it was supposed to be a BIG-IP, not a BIG-REJECT! This virtual server is more like a BIG-OOPS if it's sending RST packets.

I agree with Rima, setting the virtual server Type to Reject would explain why users are receiving TCP RST packets.
EL
Elinore 2 years ago
Option B is the correct answer. A TCP RST packet is sent when the virtual server is set to Reject, indicating that the connection is being actively rejected.

I think the possible reason could be that the virtual server Type is set to Reject.
