C might be a factor, but D feels more right based on the symptoms.

Janessa 2 months ago

B seems unlikely. If it was, no one would connect at all.

Jonelle 2 months ago

I agree, but A could be a problem too. Firewalls can be tricky.

Phuong 2 months ago

I think it's D. WS1 being standby could cause issues.

Eun 2 months ago

B could be a factor too. If the gateway is down, connections will fail.

Lili 3 months ago

I'm leaning towards A. Firewall drops could explain the failures.

Judy 3 months ago

I agree, D makes sense. Standby might not handle traffic well.

Justine 3 months ago

I think it's D. Active/standby setup can cause issues.

Cecily 3 months ago

C could be a factor too. Wrong LB method can lead to uneven traffic.

Veronika 3 months ago

I'm leaning towards A. If the firewall drops packets, that’s a big issue.

Wenona 3 months ago

I agree, D makes sense. Standby might not handle traffic well.

Jerry 4 months ago

I think it's D. Active/standby setup can cause issues.

Tamera 4 months ago

Load balancing method could also be a factor here.

Tresa 4 months ago

Surprised to see intermittent issues with that config!

Alecia 5 months ago

Active/standby setup could definitely cause this.

Janella 6 months ago

I disagree, it could be the default gateway.

Jeff 6 months ago

Looks like the firewall might be the issue.

Jeannetta 6 months ago

I think it’s just a configuration error with WS1.

Hillary 6 months ago

Wait, are the pool members really set as active/standby? That’s surprising!

Gilberto 6 months ago

Definitely sounds like a load balancing problem to me.

Leigha 6 months ago

I disagree, it could be the default gateway.

Vannessa 7 months ago

Looks like the firewall might be the issue.

Alease 7 months ago

I’m a bit confused about the default gateway option. I don't recall if that would directly cause intermittent issues like this.

Adelina 7 months ago

I'm leaning towards the active/standby setup being the issue. If WS1 is standby, it might explain why some clients are having trouble connecting.

Margery 7 months ago

I think the load balancing method could be a problem too. We practiced a similar question where the LB method caused uneven traffic distribution.

Justine 7 months ago

I remember we discussed how packet drops could indicate firewall issues, but I'm not sure if that's the only factor here.
