We want to deploy IPSec VPN Tunnel between PFSense and Zyxel UGS 1100.
After many hours of tests, we can't connect Tunnels.

According to https://doc.pfsense.org/index.php/IPsec_Troubleshooting it seems to be from the negotiation mode (main / aggressive).
We change all configuration parameters between the two routers without success.
I can publish all the configuration parameters we used, if wanted.
Is there anybody who knows this error and how to troubleshoot that situation ?
