L2TP passthrough

I'm trying to configure L2TP passthrough for my VPN what is on my LAN (Synology NAS).

Modem <-> LEDE router <-> NAS/VPN

I 've configured ports forwarding (UDP 1701, 500, 4500) and opened these ports (Traffic rules) via LuCI, but i cannot establish connections from outside my network to connect to my VPN...

I've checked the wiki (firewall settings) , but i'm not confortable with this mostly advanced documentation. However i think my config is correct.

Can you help me?

The "IPSec passthroug" section at the end of that page (https://lede-project.org/docs/user-guide/firewall_configuration#ipsec_passthrough) seems pretty straightforward.

Thank you for you're answer. However my /etc/config/firewall already have these rules...

Well, what do the logs say?
