Question

Trouble with the access to my Forti web interface

Hi everyone,

I'm having a problem when I'm trying to access my Forti web interface through my network. It's accessible when I'm connected localy and the gear under it can be pinged and accessible through the network. My managment interface is situated in a VLAN reserved for every managment access in my network. Also I have two forti101E in HA mode active/passive, and therefore only one address for my mgmt interface. The ping, http and https are activated in my configuration. If you need any other info for troubleshooting, please feel free to ask me.

Thanks in advance for your answers

hi,

maybe, https://community.fortinet.com/t5/FortiGate/Technical-Tip-Default-route-via-HA-reserved-management-Interface/ta-p/255819 will help.

also, if you have the local defined Administators defined with trusted hosts, make sure the IP or network from which you are trying is defined in it.

Hi !

I have tried to change the address of my mgmt interface so it is not in any of my subnet anymore. I still cannot access it but the material below is still pingable from my network (the cloud image). I hope the scheme will help you understand my problem a bit more, I tried to use the dedicated management interface reservation but it doesn't seem to change anything. I also tried to use the diagnose sniffer packet command and it seems that I receive request but doesn't send a reply.

Thanks in advance

can you share some output/commands for more info ?

 

diagnose debug enable

diagnose debug flow filter saddr SRCIP

diagnose debug flow filter daddr MGMTIP

diagnose debug flow show function-name enable

diagnose debug flow trace start 100

 

to stop:

diagnose debug flow trace stop

diag debug disable

 

start those and try to connect to it, then post the output here, please.

 

also:

get router info routing-table details SRCIP

and the firewall policy for: srcintf LAG(port15-16) and dstintf mgmt 

show firewall policy ID
