Ping my LAN failed

[mazu74]

Hi,

From my Fortigate 90d i can't ping any ip adress on my LAN. Why?

I want to use my local LAN DNS instead of FortiGuard Servers but can't ping them.

LAN is connected to internal1.

My LAN : 192.168. 56.0/24

Internal1 : 192.168.56.4

Thanks

Can you explain a bit further, there is not much anybody can do if we don't have more details. What's the IP address of the DNS server you are trying to reach? Is it reachable by another client in your LAN. How do you connect to your FortiGate, is this working without any problems in your LAN?

The ip of the dns is 192.168.56.9.

From another client in my lan, the ping works.

It is ping from Fortigate --> 192.168.56.9(and all other client on my lan) with the cli console

How do you connect to the FortiGate?

It seems that the firewall is not connected properly to your layer 2 network. Can you post the output of:

get system arp

I found. A VLAN with the same ip 192.168.56.4 witch give access to one PC. Down and ok. Up and stay ok.

Priority order access to the LAN had returned to internan1.
