SecuExtender is not supported on MacOS 15 (Sequoia)

Hello

We are using SSL VPN in SecuExtender ; what could be the configuration to apply on Mac OS to replace the no longer working client ?

See this thread where I describe a working solution for VPN using the free, native VPN client in Mac OS 15:

I'm trying to configure L2tp over IPSec, I think I have the problem that my firewall is behind a NAT router.
I read that you have to set a NAT on the firewall but I don't understand how, any help?

basically the connection happens, it activates, but after a few seconds it closes

Hi @Alex_91,

May I know:

1. Did you configure the NAT rule on your firewall or your router? Please note that the NAT rule should be configured on the top/upper/outer device since it has the public IP address.
2. What NAT rule did you set?

Alex_91

Full NAT from router to Firewall.

in fact I can connect to the firewall web interface, there is already an active connection IPSec site to site in this moment and working fine.

initially the l2tp did not work (it gave an error phase 2 mismatch), I had to set in phase 2 → policy public IP, now it connects for a few seconds then the connection closes.

Question: what rule must be set in Policy Route? and in the firewall?
