Issue Description

No internet activities were detected in IAM when PC access Internet, causing policy not working.

Handling Process

1. It is a new deployment. Check policy configuration is correct on IAM.
2. Check Status > Internet activities on IAM, found that no traffic was detected.
3. From PC ping to 8.8.8.8, and capture packets on IAM for both LAN (eth0) and WAN (eth2) ports (bridge mode).
4. Found that only reply packets were captured on LAN and WAN ports of IAM:
5. As per checking from above, we had tried to ping to public from the PC and capture packets in IAM, and we found that neither LAN nor WAN ports has received the ping request packets, but only received reply packets from WAN and LAN, meaning that it is one way traffic going through IAM, therefore IAM unable to block applications. It must be a two way traffic to allow IAM to recognize the traffic type and block it. Need to check the routing on the device connected under IAM and see why the request traffic is not going through IAM.

Solution

1. Ask user to check the routing on the device connected under IAM and see why the request traffic is not going through IAM. Bridge mode IAM does not perform any routing function.
