Question

network outage after fgt and fortiswitch are in place

Hello,

 

I have a very strange situation.

I installed a FGT-51E and FSW-124E-FPOE with 6.2.3...

Since these systems are running users are reporting that they will be kicked out sometimes from the network. RDP sessions will be closed, program which are running on the server will be closed etc. And that is happening while they are working.

Very strange. I configured a ping test and during the "outage" the ping did not stopped.

I have no idea how to check what could be the root cause for that.

 

I configured two vlans (office and server) and assigned them as native vlan on the switch. Is this the correct way how to do that? On the firewall there is policy which is allowing the traffic without any restrictions.

Recommended use FortiOS 6.0.9 and SwitchOS 6.2.3 cause Resolved Issues

I believe you need to leave your native vlan (vlan1) alone in that Native VLAN field, and add the appropriate vlan (Office or Server) in the Allowed VLANs field.

very strange situation.

I had configured AD collector and after we disabled that the connection is now stable. I have no idea why the collector caused such network issues.

 

Thanks for the help.

What interface was the AD Collector using? Providing more details we can probably see what's up.
