Hello Everyone,
I changed the fortinet device interface settings unintentionally.
I have changed the subnet from LAN to WAN and lost access to interface.
I got a console cable and can connect to fortigate via Putty terminal.
How can I reverse this?
Below is my system info; your help is much appreciated.
# show system interface

Hi @ExPORT,
What was the previous settings? Do you have a backup configuration before making changes? Do you know what was the IP address of the wan interface? Was it using static or DHCP IP?
Regards,
Hello Dear, It was 192.168.1.1:500 but now I cannot access through this. I omit taking a backup. I ned a remote session, would you minf helping me?
Hello,
After changing interface role some configuration may be lost. In case of reverting interface role, some configuration may not revert. Therefore, after reverting interface role it necessary to check backup of the configuration for lost configuration.
Can you please do a remote session, I managed to access the devide through console cable.
