Unable to access HTTP & HTTPS

[thanhlb]

When I switch from passive to active, I can't access the application via http and https. But I can ping and telnet the application via port 443

Hello @thanhlb

thanks for post.

Would it be possible to provide more details?

- What is name of the application? What do you see in Traffic / URL logs?

- Since there is different behavior between active and passive Firewall in HA pair, could you make sure that both Firewalls are in HA Sync status?

Kind Regards

I using ESXi application. With same VLAN I can access, but different VLAN I cannot access.

Hello @thanhlb

thank you for reply.

As a next step I would check Traffic logs to see difference between both VLANs.

Kind Regards

@thanhlb,

Validate in your traffic logs if you're seeing traffic from the other VLAN or not. It sounds like you're likely running into issues because you haven't enabled Promiscuous on the network interfaces on the ESXi side of things.

Hello PavelK

The traffic I see is still going right. I can still telnet to esxi with port 443.

Hello BPry,

I don't think so. Because when I reactivate device 2, I can still access it normally. This shows that there is no need to enable Promiscuous mode.
