Fortinet intervlan issue 7.4.11

Hi,

Which product and model are you using please?

Anthony

maybe this due to https://docs.fortinet.com/document/fortigate/7.4.11/fortios-release-notes/78623/policy-check-required-for-hairpin-traffic 

try enabling it back

Hi Fazil08,
 

Could you please provide a brief explanation of the issue along with the relevant sniffer and debug command outputs for reference and further analysis?
 

Starting from firmware 7.4.10, the behavior seems to have changed. You therefore need a rule that specifies the source and destination interface as LAN. The default setting for allow-traffic-redirect and ipv6-allow-traffic-redirect has been changed from enable to disable

If you have found a solution, please like and accept it to make it easily accessible to others.
