SSL VPN Guide

Itans

Hi,

We have many customers using Flex series firewalls and we have configured L2TP VPN using windows client.

Now it seems that L2TP is deprecated and would be better to find modern solutions.

I have tested IkeV2 with windows client and it works, but I'd like more streamlined solution like fortinet and other firewall vendors do (just install VPN client and log in with domain username/password.

I have found several guides to configure Zyxel Firewall with secuextender, but none of them seems to work or be relevant. I have made a lot of testing with secuextender and haven't got good results.

What I need is good guide howto:

• Configure firewall to use secuextender SSL VPN (no nebula)
• Use windows AD credentials to authenticate secuextender clients
• Configure secuextender to connect to firewall and get local network resources to use

Is there guide how to do this?

Hi @Itans,

May I first confirm the exact firewall model you are using?

The reason is that the currently available SecuExtender SSL VPN licenses are only supported on the USG FLEX H series firewalls.

For the previous ZLD firewalls, SecuExtender was supported in the past, but the SSL VPN license for these models is no longer available for purchase.
