How to view network traffic for ssl vpn connection

Hello expert,

 

I configured a ssl vpn remote and was successful able to establish a remote session  from my laptop.

how can i view the entire logs for any attempt from my laptop to resource on the "lan" network behind the FortiGate.

I search under log and report  forward traffic unsure if I  am searching the correct place but I am not seeing any  inbound traffic.

 

I humbly request some guidance.

 

Thanks 

 

Regards

It depends on your FortiOS version on the FGT if you want to use GUI to sniff. But check this KB:
https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-Packet-Capture-on-FortiOS-GUI/ta-p/1...

If you're ok with CLI, it has't changed almost since the inception of FGT.

No. You wouldn't be able to see user traffic on the client machine side because it's encrypted by SSL/TLS. Only way to see/sniff the traffic is on the FGT side before encryption/after decryption.
