anybody having experiences with FVS336G and L2TP/IPSec behind a NAT Router? I already tried with a certain Zyxel model, but finally it wasn't able to make it, so i threw 350,- out of the window... THX for your ideas, Jorge
Model: FVS336Gv3|ProSafe dual WAN gigabit firewall with SSL and IPSec VPN
Re: FVS336G VPN with L2TP/IPSec behind a NAT Router
Hi JEstrellas,
Welcome to the community! 🙂
Does you NAT router have a DMZ port? If it has, connect the FVS336Gv3 to the DMZ port of your NAT router and configure WAN-DMZ rules if needed.
If ever your NAT router does not have a DMZ port, you may try to open ports on the NAT router to allow L2TP VPN or IPSec VPN.
If ever you have already tried the suggestions I mentioned above and your NAT router is a combination of modem and router, you might need to configure it to full-bridge mode so that the FVS336Gv3 will be the main router which would be really suitable for L2TP VPN and IPSec VPN.
