I have FGT300D, her power is off, I installed two transceivers FG-TRAN-GC (her out-put is RJ45) in the port SFP (port 5 and port 6), then, I start the power on.

I configured port5 (192.168.1.254/24) and port6 (192.168.5.0/24), each port is in her LAN, I put PC1 or switch2 in port5, it’s connected, if I put PC2 or switch2 in port6 will be connect and will be down after 4 seconds

If I reverse interconnection PC/switch, I connect PC1 in port6 then PC2 in port5, the PC1 is connected and the PC2 not connected (same problem).

I conclude, if I install two transceivers FG-TRAN-GC in Port SFP, one port will be connect and the other port will be not connect.

No paramters are needed, they work right away. You might want to try to set speed to a fixed amount at the interface configuration with "speed 1000" and see if that improves the situation. Both transceivers should work independently from each other, so it seems to be a misconfiguration.

You configured port5 and port6 each with a different subnet, but both are in the same LAN? What do you mean? Are you using a virtual switch called "lan"?
